+ * ThreadManager class
+ *
+ * This class manages a pool of threads. It uses a ThreadFactory to create
+ * threads. It never actually creates or destroys worker threads, rather
+ * it maintains statistics on number of idle threads, number of active threads,
+ * task backlog, and average wait and service times and informs the PoolPolicy
+ * object bound to instances of this manager of interesting transitions. It is
+ * then up the PoolPolicy object to decide if the thread pool size needs to be
+ * adjusted and call this object addWorker and removeWorker methods to make
+ * changes.
+ *
+ * This design allows different policy implementations to use this code to
+ * handle basic worker thread management and worker task execution and focus on
+ * policy issues. The simplest policy, StaticPolicy, does nothing other than
+ * create a fixed number of threads.

+/**
+ * JSON protocol for Thrift.
+ *
+ * Implements a protocol which uses JSON as the wire-format.
+ *
+ * Thrift types are represented as described below:
+ *
+ * 1. Every Thrift integer type is represented as a JSON number.
+ *
+ * 2. Thrift doubles are represented as JSON numbers. Some special values are
+ *    represented as strings:
+ *    a. "NaN" for not-a-number values
+ *    b. "Infinity" for positive infinity
+ *    c. "-Infinity" for negative infinity
+ *
+ * 3. Thrift string values are emitted as JSON strings, with appropriate
+ *    escaping.
+ *
+ * 4. Thrift binary values are encoded into Base64 and emitted as JSON strings.
+ *    The readBinary() method is written such that it will properly skip if
+ *    called on a Thrift string (although it will decode garbage data).
+ *
+ *    NOTE: Base64 padding is optional for Thrift binary value encoding. So
+ *    the readBinary() method needs to decode both input strings with padding
+ *    and those without one.
+ *
+ * 5. Thrift structs are represented as JSON objects, with the field ID as the
+ *    key, and the field value represented as a JSON object with a single
+ *    key-value pair. The key is a short string identifier for that type,
+ *    followed by the value. The valid type identifiers are: "tf" for bool,
+ *    "i8" for byte, "i16" for 16-bit integer, "i32" for 32-bit integer, "i64"
+ *    for 64-bit integer, "dbl" for double-precision loating point, "str" for
+ *    string (including binary), "rec" for struct ("records"), "map" for map,
+ *    "lst" for list, "set" for set.
+ *
+ * 6. Thrift lists and sets are represented as JSON arrays, with the first
+ *    element of the JSON array being the string identifier for the Thrift
+ *    element type and the second element of the JSON array being the count of
+ *    the Thrift elements. The Thrift elements then follow.
+ *
+ * 7. Thrift maps are represented as JSON arrays, with the first two elements
+ *    of the JSON array being the string identifiers for the Thrift key type
+ *    and value type, followed by the count of the Thrift pairs, followed by a
+ *    JSON object containing the key-value pairs. Note that JSON keys can only
+ *    be strings, which means that the key type of the Thrift map should be
+ *    restricted to numeric or string types -- in the case of numerics, they
+ *    are serialized as strings.
+ *
+ * 8. Thrift messages are represented as JSON arrays, with the protocol
+ *    version #, the message name, the message type, and the sequence ID as
+ *    the first 4 elements.
+ *
+ * More discussion of the double handling is probably warranted. The aim of
+ * the current implementation is to match as closely as possible the behavior
+ * of Java's Double.toString(), which has no precision loss.  Implementors in
+ * other languages should strive to achieve that where possible. I have not
+ * yet verified whether boost:lexical_cast, which is doing that work for me in
+ * C++, loses any precision, but I am leaving this as a future improvement. I
+ * may try to provide a C component for this, so that other languages could
+ * bind to the same underlying implementation for maximum consistency.
