Update obsolete comment about pg_usleep() accuracy.
There are still some systems that use traditional tick-based sleep
timing, but many including Linux, FreeBSD and macOS started using high
resolution timer hardware more directly a decade or two ago. Update our
comment about that. Also highlight that Windows is like the older
Unixen in that respect.
