Thanks Dieter.  As it happens, I'd already stumbled across cgi.FieldStorage,
but got a bit lost I'm afraid.

I tried --

import cgi
import StringIO
s = StringIO.StringIO('my test stringio')
f = cgi.FieldStorage(s)
--

but that's as far as I got.  I'm not convinced that actually works, but as
it happens, I solved the problem by simply passing in a StringIO object
instead of a fileupload instance.  That solution was thanks to Gregor.

thanks for the pointer.
