Thanks, that looks good. My only objection would be the additional fork() 
implied by 'later'.
I'll try to get it running with that approach and do some benchmarking. Later, 
I'll try to compare that to a patched version that uses vfork() instead of 
fork() and see if that makes a difference.
Another option to avoid the fork() would be to have a pool of pre-forked 
instances reading from a jobs queue or something like that (perhaps taking 
advantage of an additional database to implement the queue?), but my skills are 
still lacking on how to implement that. I'll worry about that if the fork() 
time is noticeable.
