Log:
SVN rev 182920 on 2008-09-10 21:30:35Z by jhb
Remove an assertion that is no longer correct with the addition of
sx_sleep(). During sx_sleep(), we drop the sleepqueue chain lock after
putting the thread on the queue but before checking for signals while
we release the sx lock. If another thread wakes up the thread that is
about to go to sleep during that window, then TDF_SINTR won't be set when
the current thread checks for signals. Thus, it isn't accurate to always
assert that that flag is set here anymore.
