One of the things where it differ's from the old deep_reload is that 
when importing a submodule, say ipbug.vm, it will not reload 
ipbug/__init__.py. I've attached another version, which tries to do just 
that and I'm using that version currently without problems.
However I think there must be an even  less complicated version.  
Clearing sys.modules and 'reimporting' the module like in the following 
code seems to work ok.
====
import sys, bbutils.textproc.spellcheck
m=sys.modules.copy()
sys.modules.clear()
sys.modules['sys'] = sys
import bbutils.textproc.spellcheck
====

Currently I don't have the time to investigate this further, but in a 
week or two, I'll  have another look at this.
