SVN rev 224177 on 2011-07-18 08:29:49Z by mm
ZFS tries to allocate blocks evenly across all devices. This means when
devices are imbalanced zfs will lots of CPU searching for space on devices
which tend to be pretty full. It should instead fail quickly on the full
devices and move onto devices which have more availability.
New loader tunable: vfs.zfs.mg_alloc_failures (min = 8)
