Unfortunately BFS doesn't provide a reliable way (yet?) to run such 
tests on it.  This might be the cause for the hangs (from bfs-faq.txt):

   3. Stuck tasks after extensive use of trace functions
   (ptrace etc.).
   [...]
   5. More likely to show up bugs in *other* code due to
   being much more aggressive at using multiple CPUs so
   race conditions will show up more frequently.
