fine, don't catch any exceptions when you do the join(), your system will 
crash gloriously.

I suggest again, that you view the thread creation and later join as the 
dispatch / results portion of a normal function call.  If you cannot see 
that as at least one possible use of threads, then there isn't any point in 
further discussion with you.

I submit the argument against throw specifications (see all the relevant 
literature).
