=head1 NAME

mimeabuse - try hard to break MIME parsing

=head1 DESCRIPTION

This is meant to be run from the MIME-tools distribution directory
as a test.  It will attempt to parse the same several messages 1000 
times each.  It does a purge after each parse, so it shouldn't fill up
your disk; however, it should be a good test for hitting resource 
limits.

I wrote this after I discovered that, under Perl 5.002 at least,
FileHandle->new_tmpfile returned an object that did not get
destructed automatically when it exited scope.  :-(
