Modified files:
sys/kern : kern_fork.c kern_sig.c
sys/sys : proc.h
Log message:
Use atomic operations to update ps_singlecount. This makes
single_thread_check() safe to be called without KERNEL_LOCK().
single_thread_wait() needs to use sleep_setup() and sleep_finish()
instead of tsleep() to make sure no wakeup() is lost.
