You're right.  The problem with simply using a name other than 
__builtin__.__import__ is that it may not be there when a pickle is 
loaded because the debugger may not be running.  This is illustrated by 
the attached failimp.py file.  Try running:
	failimp.py debug dump
	failimp.py load
This simulates creating a pickle when the debugger is running and then 
trying to load it when the debugger is not running.  The workaround is 
to set __module__ to '__builtin__' and __name__ to '__import__' on the 
import_hook function.
