OK, I found the error. Aparently, the message that I was sending didn't have a
newline at the end, and so socket_read on the other end failed to complete
it's task, and finds it self with a conection reset by pear when the client
tries to write something else.
I found out when looking at the Net_Socket Object in PEAR, and say that the
was a write() and a writeLine() method in the class, an after trying it out,
it worked!
Sorry for the noise. :-)
