Just like with other exceptions, I would have exception handlers deeper
in the code if there was a section that needed to exit with a known
state.

I found an interesting thread in the Sun forums: 
http://forum.sun.com/thread.jsp?forum=5&thread=3466

Apparently the Sun C++ compiler does support throwing exceptions from
signal handlers (unofficially and unsupportedly).  So now I know that at
least some other people have had the same idea (and for the same
reasons, it sounds like.).

I will probably just check global flags for now.  That seems like much
less work than adding multiple threads to a program that currently
doesn't use them.
