Well, I can see at least one rather big problem with bgfsck (or with snapshots 
to be more precise): inappropriate time of file system lock on snapshot 
creation. On not-too-big 300G ufs2 not-too-heavy loaded snapshot creation time 
is 20+ minutes, and 5+ from that file system blocked even on reads.  This looks 
unacceptable for me for any real use.
