If you mean "os.spawnXX" I think that, under Unix, those *are* fork & 
exec, so no - they're identical.

I don't think there's a native unix syscall "spawn".

Seems I recall there is something in the MS VC runtime named similar.

Anyway - if we're talking about Twisted, you want to use the Twisted 
support - reactor.spawnProcess and a subclass of t.i.p.ProcessProtocol 
to talk to the child worker.

reactor.spawnProcess does the right thing(tm)
