I need to look for time to do the MFC, it is not too easy,
because it changes kernel and adds a syscall, touches libc,
libthr and some header files.

Hi David,
Would you consider MFC'ing your commit in rev 239347?
It'd be very useful to us if it were included in stable/9.

To properly provide CLOCK_THREAD_CPUTIME_ID, CLOCK_PROCESS_CPUTIME_ID
and clock_id's created by clock_getcpuclockid() and pthread_getcpuclockid(),
we need a kernel support.
See also #665287.
The kernel support is available in HEAD (but not in STABLE-9).
It should not be to hard to backport kernel part of
http://www.freebsd.org/cgi/query-pr.cgi?pr=168417
into our kernel.
The FBTL based libpthread will use only this interface,
it will not fallback to TSC timers at all.
The reason is that TSC part is fragile and unaccurate.
