[matplotlib-devel] Filehandle leaks in font_manager.py (was: PDF backend problem)

[<jk...@ik...>]

[Moving to the devel list.]

Here's a patch for font_manager.py to close opened files. Could
somebody review the patch? As I mentioned earlier, I don't understand
why cPickle/pickle is not imported at the top level, so I'm hesitant
to check this in without review.
