I think this is caused by a "pthread_join", most probably the one in
"stop_finalization_thread" that is called right before forking a new
process. The fact that we hang here probably means that the finalizer
thread itself is hanging, not sure why.

It looks like what was reported by Ludo here:

Thanks,

Mathieu
