more than one snapshot prevents sync.

I don't know how exactly to frame this, but I've discovered that more
than one snapshot on large filesystems (55 and 99 gig) prevents the
sync that happens at shutdown from doing anything... it doesn't print
out any numbers at all.

I have smaller (< 1G) filesystems that don't seem to be affected by
this problem... but it's 100% repeatable on the larger filessytems and
appears to affect both this week's current and a current from Aug 1st.

Dave.
