Yeah, I got enthusiastic about implementing linuxthreads, and put in
support for parisc style spinlocks using ldcw (Load and Clear Word).
We need to grab a lock by clearing it so the locks need to be initialised
to non-zero, which is exactly opposite to other glibc spinlocks. My
enthusiasm waned when I hit a missing syscall - forget what it was now.
