Synchronization: Support true relative timeouts using the POSIX
proposed standard pthread_cond_clockwait() and sem_clockwait().
These are currently implemented in glibc >= 2.30.
These methods take a clock and use an absolute time with reference
to that clock, so KernelTimeout now can produce these values.
