Demonstrating that it's possible to code pthreads in terms of the native 
Mach API.

And NPTL demonstrates that it's possible to code pthreads in terms of the 
native Linux kernel API.

This is the whole point of an abstraction. The only reason we aren't using 
it on Windows is because Microsoft doesn't supply it. The performance 
arguments are a post-hoc rationalization.
