Nice.  Even more OT, we have a student working on supervisor in GSoC who intends 
to create a "fg" command which will allow you to foreground any process from 
within supervisorctl and communicate with it (e.g., no more stopping the zope 
process under supervisor just to be able to use pdb; set.trace()).
