The compiler does not warn... But it is safer to move mono out.
I've committed the changes to the _lpw_park syscall to be able
to specify the clock, and relative or absolute like clock_nanosleep,
but I was told to hold off using it because there could be other
changes to _lwp_park, related to races with cond sleeping and
priority inversion. Do you have any ideas about that?
