Argh. Reading the code more carefully reveals that prepare/commit may be newer
(in the sense that it stems from zodb-4), but apparently is scheduled for
deprecation, since the DataManagerAdapter (which adapts prepare/commit to tpc_*)
says "TODO: deprecate for 3.6".

So, my plan now is the following:
1. write the BlobDataManager according to tpc_*.
2. deprecate the DataManagerAdapter while I'm at it.

Thoughts?

Thanks,
