But presumably you made that commit because it fixed some platform?
The default clock for pthread_cond_timedwait() seems poorly specified,
I'm not able to find any definitive statement about what it uses, and
pthread_condattr_setclock() seems to be option in the pthreads spec.
Seems to be a mess.
Anyway not sure what the best idea is....
