This will >be turned off once we import ZFS into FreeBSD-CURRENT. Ah! I did not do this. My bad, I've made the edit, and will be recompiling today to see the differences this makes. I will also clone my disk, turn witness and full debug back on, and then try and find out where my problems importing a pool with multiple cache/log devices comes from. It's quite possible it's not hanging, just taking forever, and I'm impatient and not letting it sit for a n hour to see if it completes. Will report back once I have numbers.
