After reading the source for softdep_sync_metadata(), I might believe this
could happen if the system tried to sync the block device for a softdep
filesystem before had synced all the files.

} I was seeing all of this and other wierdness when I had mfs's mounted
} on /tmp and /var/tmp.

I don't know why MFS would have an effect on this.  The only two things
I can think of are either swapping to a file on a softdep filesystem, or
somehow the softupdates stuff thinks it should be active on the MFS
filesystems.  What does /sbin/mount say about the mount flags on these
filesystems?
