Another issue similar to ITS#8264 and ITS#8299, but this time using mdb_cursor_del inside of the cursor causes corruption. mdb_del causes corruption as well, but this is the first time that I have seen mdb_cursor_del do the wrong thing.
In this case, mdb_cursor_del incorrectly removes one extra key (a key prefixed with 0c000000000000003a...) in addition to correctly removing all of the keys that begin with 0d000000000000003a.
mdb_del does not remove that extra key, but instead fails to remove two 0d000000000000003a keys that should have been removed.
I am not sure if these are two different bugs or if they are caused by the same underlying issue.
Similar reason, two different mistakes. Fixed now in git.
mdb_cursor_del performs correctly on subsequent runs if you do *not* remove the database between tests, whereas mdb_del continues to fail, but stabilizes on a different set of results after the first run.
