Hi Omri,

Another option (which I've had some success with) is using BackgrounDRb 
to manage a separate worker process which consumes items from a work 
queue. This worker process can be multithreaded. Your web app processes 
(mongrels or otherwise) would add work jobs to the queue using 
BackgrounDRb's IPC mechanisms. The work queue could be a database table, 
or maintained in memory by the worker process.

Cheers,
Pete
