Nevermind me, I must have been lacking some sleep :) You're right, the test spawns 10 threads (and those are the only ones that aren't joined immediatly), then, each thread + itself tries to spawn + join a thread... > Have you noticed the test behaving differently?

Then, I have no idea why it would fail. 12~23 threads is well within any limit set up on my system, as far as I can tell... Sorry for wasting your time, Thibaut Girka.
