If you want Python to forget about module tmp1: del sys.modules['tmp1']
But most of the issues with reload apply too http://docs.python.org/lib/built-in-funcs.html#l2h-61

See http://docs.python.org/ref/import.html to see how the import statement works, and PEP 328 http://docs.python.org/whatsnew/pep-328.html to see how using relative imports can help in this case, but not without some help from the external modules themselves.
Anyway I don't understand your usage of execfile. Maybe you're after some form of plugin system? (search past messages with those keywords)
