Is there something else besides this patch that needs to be
done/patched/configured to get higher resolution timers?

I am running the current gnumach Debian package which (to the best of my
knowledge) includes this patch, but clock_getres() still reports
10000000 ns timer resolution and applications like PostgreSQL that rely
on timing still have 10ms resolution.
