Yes, I remember now. But ...

I understand. But I also thought that it would be nice to avoid printing
the frames that are relative to thread startup code, and start the
backtrace at the function the code used in the pthread_create call
for instance. I think that the user won't be interested in them most
of the time.

That was part of my motivation. No big deal, I'll solve the other
issues the recommended way the next time I come across them.
