I've seen the crash happen at least twice now after running the 
regression tests, so I think it is reproducible.  I haven't attempted to 
simplify the steps required to make it happen.  I'll try to look into 
that.  From looking at the bjam.log file, it is almost my impression 
that all the regression tests have completed and the crash happens when 
bjam tries to exit.  But I need to confirm that.

The last test run checked out the trunk at revision 79587.

I'll try to do some preliminary investigation and if I don't come up 
with anything sensible, I may have you take a look.
