* Don't use sysexits.h. Just exit 1 on error and 0 otherwise. * Don't sacrifice precision by converting the output of clock_gettime() to a double and then comparing the results. Instead, subtract the values of the two clock_gettime() calls, then convert to double. * Don't use CLOCK_MONOTONIC_PRECISE. It's an unportable synonym for CLOCK_MONOTONIC. * Use more appropriate names for some local variables. * In the summary message, round elapsed time to the nearest microsecond.
