 I simply tried again without changing the kernel, and let it run. It
 eventually completed. (straw clutching: could kern/53124 also apply
 to zfs - 4 cores 8 threads)
 
 Back to the PR:
 
 # zfs list -t snapshot
 NAME              USED  AVAIL  REFER  MOUNTPOINT
 bpi/pkgsrc@orig  47.4M      -   403M  -
 # zfs diff bpi/pkgsrc@orig
 
 caused a freeze with nothing appearing on the console. Of course
 this box doesn't even have a serial header on its motherboard.
