Depends on what you mean by "hang".  The DNS lookup can a take long time to 
give up.  The problem I'm chasing takes longer than that.

What I was expecting was that ^C would get me to the debugger so I could get 
a stack track.  It doesn't seem to work that way.  Or I missed a key step, or 
...  It gets me to the debugger, but the stack is garbage.

If a python program is hung, how do I find out where?

There is another bug/quirk in ntpq.  In interactive mode, it needs a ^C 

These are my opinions.  I hate spam.
