Given our current discussion to change cancelable_wait, does it make
sense to review this patch?  AFAICs the clock_nanosleep function will
have to be changes quite a bit, right?

Something else occured to me, but I think we should do this in an extra
step, if at all.  IMO the family of sleep functions should be moved out
of signal.cc into times.cc.  It just seems to belong there.
