Under what circumstances is taking a trip through 1-2 extra gen_servers
is faster than pushing data directly to the socket?

I do have a transport (protocol handler) process and I do have a session
process that persists even while the socket is gone. I used to send
to the session which would forward to the transport and I still do this
for HTTP since the socket does not persist.

I decided to optimize away the extra trip through session and transport
for persistent Flash connections, though, by capturing gen_tcp:send
with the socket in a closure and using that to push to the socket  
directly.

	Thanks, Joel
