Delete it from sys.modules:

 >>> file('foo.py', 'w').write('x = 42\n')
 >>> import foo
 >>> foo.x
42
 >>> del foo
 >>> import sys
 >>> del sys.modules['foo']
 >>> file('foo.py', 'w').write('x = 999\n')
 >>> import foo
 >>> foo.x
999

Beware that if you still have old references to the module, they 
don't get refreshed.
