That program exposes another leap second bug, too, I think. It reads
the time via adjtimex in a tight loop, optionally sleeping using

	clock_nanosleep(CLOCK_MONOTONIC, 0, &ts, NULL);

The program does not wake from this call during a leap second. It is
my expectation that CLOCK_MONOTONIC should always work. Why doesn't
it?

Thanks,
Richard
