Since the error does not affect ircd->irc_client data flow but
only blocks irc_client->ircd flow, I would suspect it is the receive
buffer size change that is killing it. Perhaps some new code incorrectly
assumes the buffer size to be something other than what ircd changes it to.
I'll continue investigating.
