Suggestion to speed up initial JSON import

[pombredanne]

Description

When I import a JSON file, I noted that the sqlite DB file seems to be flushed on disk incrementally and I can see the sqlite file grow as the import goes.
I have an idea: if you import to a memory only database and once this is all imported and only then you save on disk this may speed things up? this may be worth a try
