Comment (by edsko):

 Yeah, I thought about that too, but I couldn't see anything different in
 the file descriptors in deadlocking runs and non-deadlocking runs -- but
 that was purely based on the file descriptor _numbers_ (9, 4, 8), so you
 may of course still be right. I didn't manage to verify or refute this :/
