Thanks for the report. I'm still not able to reproduce the problem, but I'll try harder with different linux versions. Do you know the libc version in your system?

I've reproduced the bug, the queue only works for single proucer / single consumer. I have a fix adding some blocked producer and consumer counters. You test case seems fixed with these counters. I'll commit it to trunk ASAP, it would be nice if you could tell me if the problem was completely solved.

Ok, I'll check my test after your commit.
