You use at least ZODB 3.2 and ensure transaction boundaries,
e.g. by calling "transaction.commit()" or "transaction.abort()".

If you do this, then (of course) you need to write the complete list.

If this lets your storage grow too fast, then probably the ZODB
is not the right storage medium for you -- or you dig up the BDB storage.
It is still somewhere in the SVN/CVS reporitories.
