As I understand it, it buffers changes until either IStorage::Commit is called,
in which case it writes them out in one go or until IStorage::Revert is called,
in which case it discards them.  Probably need more test cases to determine
exactly how it works.

It's probably not trivial to implement transacted storage.  I think Microsoft
implements it using temporary files and temporary streams...
