There used to be a time when the Hurd didn't have pthreads at all -- but
this changed many years ago with Neal's pthreads implementation.

The remaining problem is that the Hurd translators and server libraries
still use ctreads, and thus programs linking these can't use pthreads.
But that doesn't apply to "normal" programs -- these just link the
client-side library (libc), which doesn't use cthreads.
