Modified files:
sys/kern kern_synch.c
Log:
Work around a race between msleep() and endtsleep() where it was possible
for endtsleep() to be executing when msleep() resumed, for endtsleep()
to spin on sched_lock long enough for the other process to loop on
msleep() and sleep again resulting in endtsleep() waking up the "wrong"
msleep.
