Well, I knew this, I knew it very well, as you can see from the code on
the git I pointed to (it's part of one of the examples!).

the thing is that I believe there are situations where it could be
useful to sample CLOCK_THREAD_CPUTIME_ID from a _different_ process, and
in that case, you can't access that thread's pthread-id, can you? :-O

The jack2 code I saw could be one of these "potential user", and AFAICT
your jack1 might be another one, no?
Yeah, I know, whether you can/want use this or not also depends on other
issues, but you are in a _different_ process --and thus you can't use
pthread_* calls-- aren't you?

I'm now looking at Oleg's solution and into glibc as well... I'll come
out with something ASAP.

Dario
