Can you briefly explain why it leaks memory?

I have been playing with Apache::Leak and Devel::Leak trying to figure out
what is happening when Perl code leaks memory, but I haven't got my head
around it yet...

Also, a more general question to the list.  How reasonable is it to assume
that most of the more standard modules on CPAN don't leak memory when used
in a mod_perl environment?  For example DBI (not to pick on you Tim),
Data::Dumper, HTML::Parser or MD5 just to name some of the more common
modules.  Are there any modules that I should stay away from when using
