I'm glad you could reproduce.  Based on your description, this sounds 
like a separate issue and not a regression introduced by the workarounds 
you put in place for the ExitProcess / ExitThread race.  Correct?

I wonder if this is the same issue I'm experiencing though.  I'm only 
pressing ctrl-c once and it sounds like you might be deliving a ctrl-c 
to the same process multiple times.  That may not be relevant to the 
root cause however.

Tom.
