 Okay, you were right.  I've found a bug that caused this problem and
 fixed it.  We should have been able to notice that sooner if we had
 unit tests for Bob.reap_children().  We could add one within this
 ticket, but I'd rather suggest leaving it to a separate ticket, and in
 a larger framework: despite its importance the Bob class and
 bind10_src.py.in in general are tested only very poorly.  I suggest
 refactoring it so the core logic will be more independent from
 system-dependent things like process scheduling, also probably making
 the Bob class more concise, and providing more tests for them.
 Providing tests for reap_children() would be part of this larger task.

 If this makes sense, and the latest branch passes the test (which I'm
 quite sure does), I'll create the followup tickets and close this one.
