Packet type MSG_UNIMPLEMENTED will be leaked if a keepalive_config is
sent before authorization is done (My code was doing this previously as
I thought keepalive should be done immediately after opening the session).
Packet type MSG_REQUEST_FAILURE will be leaked every time a keepalive is
sent when the keepalive_config was set with want_reply (2nd parameter)
set to 1. This was the cause of the massive leaking that occurred. I
just set that second parameter to 0 and there are no more leaks.
Neither of these message types is handled appropriately, so they will
always be leaked.
I think there was some discussion about keeping track of
request/response packets to map unimplemented and request failure
responses back to the requesting API. I have no suggestions on that
point, but there were some other discussions in the thread if your
interested.
