Source Thread Fix v1.1

Yeah, already. I did somme small woopsies, and now fixed the woopsies.
So, this is essentially just an optimisation release - hopefully the
last one, but realistically, probably not. :)

Source Thread Fix v1.0

It does what it's meant to do. Not really much to say. I don't expect
there to be that many more releases either. It's done, really. I'm sure
that will end up changing in future, but for now, this is it.
