I tried clock_gettime() (using CLOCK_REALTIME for clock_id), but this

Try CLOCK_MONOTONIC instead.
I forgot - there are also the FreeBSD-specific CLOCK_REALTIME_FAST and
CLOCK_MONOTONIC_FAST if you can live with a little bit of jitter.
Not to discount any of your suggestions, but isn't the better
performance of gettimeofday() (and perhaps clock_gettime() also)
in Linux because they have access to the time in userland and
can implement it without a system call? I seem to recall this
being mentioned before, I could be wrong...
