The list isn't that long. What distinguishes those interfaces is that they
can't be implemented on top of, e.g., the stdio implementation. The original
question, as I understood it, was whether the general architecture of
Windows was a reasonable fit for a POSIX threads implementation. Most of the
library can be implemented without unwarranted chumminess with the
underlying implementation, and the remaining pieces--with signals being the
biggest question mark--would appear to require only minimal cooperation by
the vendor.

Not that I believe C1x should adopt pthreads, mind you. Also, the proposal
was qualified--it suggested adopting a _subset_ of pthreads.
