My view is that spurious wakeup is a separate item in this list. "The
specified amount of real time has elapsed" should only be about "normal"
timeout.

 377      * <li>The specified amount of real time has elapsed, more or less....

 382      * <li>Thread <var>T</var> is awakened spuriously. (See below.)

I feel that "returning early" should occur only for rare spurious wakeups
(and I'd like even those to go away someday).
