When memory usage is a concern, is it better to do:

from X import Y

or

import X

Also, is there a way to load and unload modules as they are needed. I
have some scripts that sleep for extended periods during a while loop
and I need to be as memory friendly as possible. I can post a detailed
script that currently uses ~ 10MB of memory if anyone is interested.

Thanks,
Brad
