The output of sysctl -a hangs on my system for seconds when it gets to printing this kstat. I've found this change https://github.com/openzfs/zfs/pull/11099/files for fbsd which mentions skipping these. Should these be skipped for release builds of o3x? Not sure if these are just intended for debugging purposes or normal use.
This is with 2.1.0 on Monterey x64.
