Modified Files:
	src/lib/libpthread/arch/i386 [nathanw_sa]: pthread_switch.S

Log Message:
Rewrite pthread__switch() and adjust pthread__locked_switch() to
avoid storing the new saved-context pointer while still using the old
stack. This avoids a race condition with pthread__find_interrupted()
where a thread could lose its old state if it was interrupted in a
certain window in pthread__switch() or pthread__locked_switch() (the
latter was never actually observed, but appeared possible).
