Not sure it qualifies as a "framework" but POE makes implementing 
something resembling what you describe relatively straightforward. I 
implemented a process queuing system circa 2004 using POE and combining 
in various other CPAN modules such as Log4perl, GnuPG::Interface, etc. 
It was an encrypted file transfer system working in both directions. So 
there was a pre-processing queue, encryption/decryption queue, 
(FTP/SMTP) transfer queue, and a post-processing queue. Each element of 
a queue forked an individual process to do its work. Each queue had a 
pre-configured maximum running size, etc. Sorry I don't have code to 
share but it'd be pretty dated anyways.
