Monks,

I was recently bit by the "Too many open files" error while doing a lot of file operations via a Perl script.

After (several hundred or thousand) file handles had been opened (and not closed), my program would just crash.

Sure - now I've fixed the problem, but it would be nice to add a unit test to check for dangling open file handles. A quick search on CPAN didn't produce anything, and without resorting to tricks like $open_filehandles = `/usr/sbin/lsof -p $$ | wc -l` I'd like to know how to do this in Perl.

Ideas?
