Hi. Yesterday one of the PCs at my university was updated to Debian "squeeze" with
kernel 2.6.32-5-amd64. I don't know if it's the kernel, hwloc or something else's fault
but I have a program tha worked fine before the update, but not anymore. It does work
without problem in other PCs.

The program uses hwloc_set_thread_cpubind() to bind some threads to specific cpus
but now it doesn't work. hwloc_set_thread_cpubind() returns zero but doesn't bind
the thread. The problem is that when I call hwloc_set_thread_cpubind() the threads
are waiting on a posix barrier.
