  ZFS does not do a config_sync after removing an aux (spare, log, or cache)
  device. AFAICT this isn't being done because it is slow and was deemed
  unnecessary. However, it should be such a rare operation that speed doesn't
  matter, and not doing it results in two problems:
  1) It is theoretically possible to remove an aux device from one pool and
  attach it to another, then lose power. When power is restored, both pools woul
d
  think that they own the aux device.
  2) Removal of the aux device doesn't send any useful sysevents to userland.
