Yes, this happens with the latest CVS.  I have not tried reproducing 
with polling based mechanism, but I don't think it would exist there.

I agree that timers are causing problems (and likely continue to do 
so), and we would be better off without them, or by implementing 
better locking when using them (anyone interested in looking at 
this?).

In order for select/poll-based mechanism to be considered, it would 
need to support all MUSTs from the spec and preferably SHOULDs also. I 
recall there was some discussion about this late last year, e.g. 
relating to random delay feature.
