What's going on is that the background file system checker hasn't adjusted
down the reference counts for the directory in question.  I've run into
this on a couple of occasions, and Kirk and I have bantered about possible
fixes.  Basically, the only inconsistencies permitted by soft updates are
freed space being unavailable for reuse, and elevated reference counts. 
The background file system checker walks through the file system metadata
in a snapshot to move blocks to the free list and adjust reference counts.
The problem will clear by itself once bgfsck catches up; as a workaround,
just move it out of the way somewhere in the same file system until bgfsck
is done.  Or you can manually clear up the reference if you're willing to
risk it :-).  A normal fsck in single-user would also clear it up.
