This is going to be a dumb question, but what would that take?

When I've referred before to a "total revamp of hurd libc", that's pretty
much it. I'd like to more or less start over on signals, the hurd critical
section stuff, and probably revisit all the locking schemes from scratch.
This is necessary to do POSIX semantics for signals, cancellation, and
their pthreads interactions, correctly and robustly.

So get to work. ;-) j/k. I'd love to take this on but probably way over my head?
