[Zope-dev] Conflict reduced BTrees for cataloging

I am working on a CMS on top of ZODB for large amounts of
large SGML/XML documents.

To speed things up, a colleague started two import processes
and we get incredible amounts of "database read conflict error"s
from cataloguing (although we already use "QueueCatalog" for
most indexes).

I think, the data structures used for cataloguing and indexing
could have a "def _p_independent(self): return 1".

Does anybody objects?

If not, I will implement "_p_independent" BTrees and friends.
