Actually, I'm looking at the kernel code here.  It looks like
posix_cpu_clock_get() should be able to handle a per-task cpu clock for
another thread within the same process.  However, it's only ever called
by thread_cpu_clock_get(), which hardcodes a clock_id of THREAD_CLOCK,
which corresponds to the current thread.

Similarly, invalid_clockid() will say that the clock_id is invalid if
it's positive but greater than 15.  If my math is right, this means that
any pid > 2 will result in invalid_clockid() failing.
