Thinking about all the non-atomic stubs we are using
in glibc linuxthreads... *shiver*. I will get around
to fixing this once I've got everything upstream.

See libc/sysdeps/generic/atomicity.h for an explanation
on the topic. We need to implement:

	exchange_and_add
	atomic_add
	compare_and_swap

The last being the most important since it's used in
glibc's linuxthreads implementation :}
