Use CLOCK_MONOTONIC_COARSE rather than COARSE_MONOTONIC_RAW.

Browse Source 
The raw clock variant is slow (even relative to plain CLOCK_MONOTONIC),
whereas the coarse clock variant is faster than CLOCK_MONOTONIC, but
still has resolution (~1ms) that is adequate for our purposes.

This resolves #479.
