+
+/*
+ A pushed stream is put into a memory buffer (The SpdyPushTransactionBuffer)
+ and spooled there until a GET is made that can be matched up with it. At
+ that time we have two spdy streams - the GET (aka the sink) and the PUSH
+ (aka the source). Data is copied between those two streams for the lifetime
+ of the transaction. This is true even if the transaction buffer is empty,
+ partly complete, or totally loaded at the time the GET correspondence is made.
+
+ correspondence is done through a hash table of the full url, the spdy session,
+ and the load group. The load group is implicit because that's where the
+ hash is stored, the other items comprise the hash key.
+
+ Pushed streams are subject to aggressive flow control before they are matched
+ with a GET at which point flow control is effectively disabled to match the
+ client pull behavior.
