FWIW, it's still very brittle on Solaris 10 and the Sun Support
response to most issues is "restore from backup".  The IMHO, the
biggest issue with ZFS itself is lack of recovery tools prior to PSARC
2009/479 (in ZFS v21).

Not in my repository.  I still have v13 in
sys/cddl/contrib/opensolaris/uts/common/sys/fs/zfs.h in last night's
RELENG_7, RELENG_8 and -current.

My understanding is that the problem is more that the FreeBSD VM
system doesn't gracefully handle running low or out of memory.
