Yes you get the benefit of shared modules. PerlRun only differs from
registry in the sense that it clears out the namespace of the main script.
As for leaking memory like a sieve? That is not unexpected with PerlRun
scripts because they are typically not coded cleanly. Hell, even our 6 year
old Extropia Perl 4 scripts will run under PerlRun. A surprise. But it
doesn't mean it is efficient.
In fact, I would suggest that you create two backend mod_perl servers, one
for PerlRun and one for your cleaner mod_perl scripts. The PerlRun server
should be set up to destroy itself after much fewer hits... so you could
still get the benefits of the shared module loading because of the
preforked module loading, but the individual apache engines can clean
themselves out sooner.
