I think I've found out what causes it. The clock on my workstation is
too fast, it needs only around two minutes and fifteen seconds to drift
ahead one second. This makes ntpd step the time backwards, which
appears to be what causes the hangs. Only happens sometimes, though,
but I observerd a clear correlation between the hangs and clock
stepping when I tested manually with ntpdate.
Even though X11R6 had no problems with this, I'm closing this bug as
it's unlikely to affect many users (it appears they'd need both to be
running Openbox and ntpd, as well as to have defective hardware).
