Ok, some more info - after running the full semaphored version all night
I got another crash so I think we can rule out a concurrency problem.
I've reduced the code into a single script with a test database but
without the web server, I'll test that a bit more then post it if I can
get it to crash too...

To answer your question, yes it's a simple serve/servlet.
