Depends very much on the protocol and the OS abilities - pthread does work
over process boundaries (but maybe not on the platform where you need it),
as does accept() and read() on a shared fd. GNUL/Linux can selectively
share the fd table without sharing anything else (but you have no good API
for that, as it isn't supported by pthreads etc.).

For your specific problem, that could well be true. Things aren't black or
white, there is grey stuff too :)
