I haven't seen it since I upgraded from r290039 Tue Oct 27 to r290224
Sat Oct 31.  I can believe that low memory would trigger it since I
often it uses zfs and I sometimes drive it heavily into swap (using
tmpfs) when running poudriere with parallel builds.  The timing makes
sense because the bug was introduce by r289279, and before r290039 I had
been running r289123 without having any problems.
