I don't know if any of these are heisenbugs, or just dependent on phase  
of the moon, but I have only had one crash (probably not the same as  
Albrecht's) in the past few weeks, and of course, that one happened  
when I was not running through gdb.  I'm also only seeing the hangs  
when running in full debug mode.
