   I suspect we should have a left shift here, rather than a right shift:

            bt.frac = (((ms % 1000U) << 32)/1000U) >> 32;

They should both be left shifts.  The point of the exercise is to
reduce ms to the range [0, 999) as a fraction of a second, and then to
convert a number of milliseconds (= 1000ths of a second) to a number
of 2^64ths of a second by

   ms*2^64/1000 = ((ms*2^32)/1000)*2^32 = (ms << 32)/1000 << 32.

This was all written for a cv_timedwaitbt API I intended to add a
while back but never got around to:
