Sorry for not responding immediately.
You're accessing the messageCount variable from two threads. That is
not safe and I'm pretty sure that's where your test gets confused.
The only safe way to send information from one thread to another is to
send a message. I'm writing a version of your code, in C, which does
this. You can try anyhow: use another pair of sockets, PUSH from the
recvThread and PULL in the main.
