Are you still seeing this problem?
I had expected that the changes around rds_destroy_pending - see commit
ebeeb1ad9b8a - would have taken care of this (note that ebeeb1ad9b8a
refactors/updates 3db6e0d172c9) but those fixes were done by inspection
only. In other words, I was never able to reproduce this, so we may
still have missed some race condition.
