Next problems, (and hope last)

I have started some Python threads, and want to wait for them to finish.

I wrote this program to demonstrate my problem. I am on a 64 bit machine, Ubuntu.

I tried playing around with GIL state but it does not change anything, so it is commented out.

when using pthreads it works (of course) when I use python threads the sleep does not work and the threads all exit on the _join
