I've had experiences with some python mail servers that time out connections
if data from the socket is not sent to the application within the timeout
parameter.
I have seen a python app on FreeBSD that would timeout a connection after
600 seconds if freebsd did not receive at least 32 kb of data within the 600
second timeout. FreeBSD would only send from the buffer to the app if there
was 32kb of data, unless TCP segments were received with the PUSH flag set
which would force a flush of the network buffer.
It sounds like this is the behavior Brendan is seeing.
