Don't assume that threads are created a la C-Threads in microkernels
!= mach. The same is true for OS-embedded environments. It's probably
safe to assume a Pthreads interface as specified by the specs.

On l4-hurd, we will most likely drop C-Threads completely in favor of
Pthreads. Pthreads are already available in most Unices (the
Hurd/VK/Unix case) and we'll use a Pthreads wrapper around the (new)
L4 threads API once it is available.

In every case, you should use the Pthreads API to get the base of the
stack. This is the only truly portable solution.
