How (often) is OGSocket::recv(...) being called - from a busy loop?

What about that _ip_delay1(m_pSock,sock_delay) ... sounds kind of
suspicious - anything with big delays happening in there?

Not sure about more recent versions of wattcp, but it used to be that
the main tcp worker 'process' tcp_tick() was running on the good old
18.18 Hz / 55 msec dos clock. You could try calling tcp_tick() [not
quite sutre that was the exact name] before recv() to be sure all 'raw'
received data has been processed and is available to fastread().

Just a bunch of hunches ;)
