Current language:? auto; currently minimal

This is currently repeatable.? What was going on at the instant in time was:
root at NewFS:~ # /root/backup-zfs/run-backup
Begin local ZFS backup by SEND

attempting destroy
backup/R/12.STABLE-2019-06-14 at zfs-auto-snap_daily-2019-07-11-00h07
success
It destroyed the snapshot on the backup volume, and panic'd immediately
thereafter.? This is an incremental send.
If I reboot the machine and re-start the backup job it will blow up when
a couple more of the incremental deletes get done.
Given the depth of the callback stack is this simply a kernel stack
exhaustion problem?? I wouldn't THINK it would be, but......
I do have this in /boot/loader.conf:
# Try to avoid kernel stack exhaustion due to TRIM storms.
kern.kstack_pages="6"
The backup volumes are spinning rust, so there should be no "TRIM"
attempts to them.? In theory.
I have the dump if someone wants me to run anything specific against it
in terms of stack frames, etc.
