Log message:
save and restore fp state when switching threads.   This, with
an arch/i386 patch previously commited and arch/sparc64 patches
from jason@ make the preemption_float test pass on those two
architectures.

Do not run signal handlers for a thread until the thread has
been made current, ensuring the proper context.   Solves several
(if not all) of the '_pq_insert_tail: Already in priority queue'
problems.
