Summary: bsddb.btopen . del of record doesn't update index

Initial Comment:
A ram -resident database is creaed with btopen

10 records are added, keyed by sequence, value is sequence + 1 (both converted to strings).

I check to ensure that all of the records have been added.

I delete the first record, check the keys again, and it still works.

I delete the first record, check the keys again, and it fails, thusly:
