A stripe of three-way mirrors works:
FreeBSD/i386 boot
Default: mithril:/boot/zfsloader
boot: status
pool: mithril
config:
NAME STATE
mithril ONLINE
mirror ONLINE
label/mithril-0 ONLINE
label/mithril-1 ONLINE
label/mithril-2 ONLINE
mirror ONLINE
label/mithril-3 ONLINE
label/mithril-4 ONLINE
label/mithril-5 ONLINE
