Don't give up hope, Ian!

We have fixed many problems related to the implementation of sockets on 
Windows (the Winsocket API has some annoying differences with the BSD 
API).

Then, there is this thread communication problem on the master gnubg.
Holger, we need to get in touch again to find out what's not working -- 
could you again spare some of your free time for me? Can you commit 
your current version, with the changes we made last time, to CVS?

This problem only occurs on a slave waiting for a new connection (which 
is not a problem as soon as rollout computing has been started). I 
intended to fix this once everything else is working fine.

At least, it works on my version of Unix (Mac OS X)
Who else tried it on any other flavor of Unix/Linux?
