Hmm. fork doesn't exist in all OS - for example I seem to recall some 
problems with regard to Windows in that area (windows only supporting 
threading under python, not forking).

And we have to take precautions if the forked process needs to talk to 
metakit databases, as those are only single-user (but it might be that 
they are only single-write but multiple-read, I didn't check that).

That's why in PyDS every tool has it's own lock object, so I can 
protect database access against background threads concurrent access.
