 My system is my laptop.  I have a script that takes a snapshot at 4 AM
 on / and /usr.  / is 256M nad /usr is 50G.  Shutdown hangs when there
 is more than one snapshot on /usr but it doesn't hang based on any
 number of snapshots on /.
 
 This is 100% repeatable.  Remvoing all-but-one /usr snapshot makes
 shutdowns work just fine.  Having more than one makes it hang on the
 buffers remaining bit.
 
 Dave.
