I thought that using your mod_perl process to handle file uploads was a 
Bad Thing.  You might want to think about using a domain cookie, and 
pass the client off to a lighter process to handle the upload, rather 
than having a giant mod_perl apache process spinning for five minutes 
while someone uploads a file.

Just my $0.02.
