Just to add - we've seen this a few times as well. Our distributed build 
script very occasionally dies with an IronPython Console crash dialog 
despite try/excepts around all of the threads of execution. It took a 
long time to actually see what the error was - it looks like it was a 
.NET file system exception resulting from a call to shutil.copyfile 
(unfortunately I didn't manage to grab the text). The traceback was from 
<somestream>.Flush - we're copying files over a network which 
occasionally goes away, so that would make sense.

(This is also IP 1.1.2 - haven't tried this with IP 2.)
