In my tests on several systems the function clock_gettime() with
CLOCK_THREAD_CPUTIME_ID doesn't return the cputime of a thread, but the
cputime of the whole process.
The sole chance to get the cputime of a thread is to parse the
file /proc/<pid>/task/<pid_of_the_thread>/stat.
This works under linux. But under AIX 5.1 I didn't find a solution.
