WHEN it returns things other than files.  Like a StringIO object,
which can be quite handy.  True, it won't be a "big file", but it'd
be nice if the same code would tolerate it.  I've used this with
e.g. PIL quite a bit when working with Zope, because it isn't
really desireable to have to write the file out to disk and read
it back when you've already got it in memory.

Quack! ;-)
