OK I think I know what might be causing this. I was taking current time
snapshot with clock_gettime(CLOCK_MONOTONIC, &ts) and I think NetBSD
pthreads implementation wants CLOCK_REALTIME. There appears to be no
pthread_condattr_setclock() function, so CLOCK_REALTIME is probably the
only option.

It might be useful to add this info to pthread_cond_timedwait man page,
as it's very easy to mix up the clock types.
