Hello,

It's been a long time since we've received such high quality
contributions out of the blue. Thanks for that :).

The patch looks fine, although I've only taken a quick look for now.
Concerning names and the interface, I'd personally advocate following
what Linux does, because Linux is the de facto current standard, and
it would make it easier to e.g. reuse the pthread glibc implementation
(some efforts regarding portability have been made there but I'm
almost positive having a semi or completely compatible interface would
help a lot). The Linux mechanism is also very well documented and
they've spent time on the tricky issues already, so we might just
avoid wasting time there.

In any case, it's definitely the right direction.
