Please, clarify this. I don't see your point.

I agree this could be an issue that need to be studied. Please, post a
new bug report for that (to be addressed in 2.6.1, I think, since this
issue doesn't crash the interpreter).

I post a patch for the bugs originally indicated in this bug report, an
another one (db.verify() regression).

*Please Review*. I will update python 2.6 svn when the review is done.
Thanks.
