I'm making a little game in rebol (internet scrabble, currently in Swedish
but could of course easily be translated if somebody is interested :) that
requires two rebol scripts to message each others.
Easy in theory. In practice, they close connection after a number of
messages. I have no idea why. :(
Here's some testing code. If I run this twice and enter 127.0.0.1
(connecting to myself) it sends a total of 121 messages, and then one of
the scripts refuse to accept a connection. I sent it to someone else, there
it made 117 messages or so. But always the same number on the same system,
it seems. I can't really explain this. What am I doing wrong?

Stop worrying so much about this. In the worst case we'll die.
