import fu; del fu complains about RedefinedWhileUnused

[Florent]

This case where we import a module for its side-effects gives a warning.

import fu
del fu

or the one of bug 1162031

import selenium as se
import selenium.webdriver
del selenium

se.webdriver.Firefox("foo")

Note that this case is covered in the test suite, so it might be intentional:
