UNEXPECTED SOFT UPDATE INCONSISTENCY; RUN fsck MANUALLY

For me, this doesn't matter because ZFS is so much faster than UFS
overall.  Even if you don't use any of its features, the latest version
does sequential I/O and heavy random I/O faster than UFS on the same
hardware for me.

Cases where UFS is faster are proving to be the exception rather than
the rule.

However, I cannot recommend its use until it is stable, which it
currently still is not, under very heavy load.
