+This feature allows zfs to postpone new resilvers if an existing one is already
+in progress. Without this feature, any new resilvers will cause the currently
+running one to be immediately restarted from the beginning.

+This feature becomes \fBactive\fR once a resilver has been deferred, and
+returns to being \fBenabled\fR when the deferred resilver begins.
