	basesrc/lib/libpthread [nathanw_sa]: pthread_sa.c

Log Message:
It is no longer necessary that a switchto's pt_next and pt_parent be
NULL. In fact, they will often not be null: a thread that hits a
new_preempt case in pthread__locked_switch() or
pthread__upcall_switch() will have itself as its switchto victim.
