[Biopython] [Entrez.efetch] save records

[Peter Cock]

Hmm. I would keep the data as the original XML, and parse it
on demand. That should work regardless of the version of
Python and Biopython (or indeed, if you switched to Ruby etc).
Python's pickles are not consistent between versions (especially
mixing Python 2 and 3).

In this case the Entrez parser objects are probably not pickle-able :(
Are you interested in trying to fix that?
