Yes, there seems to be a LARGE memory leak. It appears that the script
forgets to call wfFreeResult when it's done with it. (Though that is
from a very short scan of the files).

I can not say what to do exactly (I am not that familar with the
code), but my recomendation would be to place a call at about line 12.
(at least, obviously much more is needed).

It's also possible that the request involves a huge number of pages
that would take 64M. (And with Wikipedia, that is possible.)
