The latest support source is in the CVS tree on the HRT site. It is no
longer a patch...

I suspect that the 64/32 div resulted in a >32 bit result which is a
fault. This was deep in monotonic_clock. I would rather change to
clock_monotonic (i.e. xtime+offset+walltomonotonic) and work that code
patch. monotonic_clock is just the wrong thing for this work.
