Certainly, however, as using the current infrastructure will require
more than a few changes, I thought it might make sense to just rewrite
it right now.

I have already implemented the pthread cancelation interfaces and
started to adjust parts of the Hurd to use it.  I am dubious of
benefits of not going directly to pthreads.
