With the patch applied, test019 sporadically segfaults after doing a delete op on an entry. Took me 12/50 iterations with back-mdb, 2/50 with back-bdb. But just 1/1 on two other occasions, so while it's not every iteration, it's fairly repeatable. I will work on getting a backtrace as well.
With the current code, test050 sporadically fails (Took me 8/50 iterations):
