[kaffe] threads problem

[Guilhem Lavaux]

Hi Ioannis,

This is good news that at least the fix seems to correct most of the 
problems. Concerning the cpu usage with pthreads I expect it is correct 
that it really eats all the CPU (actually your test is meant to no ? :-))

The problem with jthreads is a bit more worrying. We really need to 
investigate this issue. I will try to run the same tests for as long on 
some computer I have to check if it is reproduceable.

Good luck with cross-compilation !

Regards,
Guilhem.
