Hmm, I'm still having problems, but mostly only under heavy system load. 
Seems a notifyOne gets lost somewhere (at least, the result is that a 
thread is waiting at a point where it shouldn't be). I've tried the 
latest SVN trunk (as the commit log said that another similar bug to the 
one I reported was fixed) -- no luck.

Funnily enough, it's exactly at the same place again where I had my 
original problem. Seems that the switch during condition::wait is not 
fully atomic or something similar, as everything should be protected by 
a mutex and yet the state I'm getting into is inconsistent. I'll try to 
investigate a bit further.

Any ideas?
