marshal doesn't work with "file-like" objects

That wasn't my intent, but I confess I don't have time or interest to flesh
it out.  Sketch:  if Chuck wants a filelike object to marshal in and out of,
he can craft a filelike object that also tucks away an index (or length
prefixes, a la Rainer's followup), so he can know in advance how much of the
stream needs to be read.

I've got no interest in seeing such cruft added to the Python core, though.
