That looks reasonable to me.  In my case, I was looking to use a
SpooledTemporaryFile to convey the output of ReportLab to pdfrw.  If the
file is small, it's better to keep it all in memory, but if it's large,
it'd be better to let it roll over to disk.   The SpooledTemporaryFile
should let that happen automatically.  I don't actually care where it's
stored, so the filename changing doesn't bother me at all.

Thanks for the quick fix,
