Bug#549691: failure removing snapshot volumes

Hi,

I'm still having trouble removing my snapshot volumes.  I recalled that
my fstab mounts are based on UUID, which are identical for the origin
and the snapshot (so much for unique ;)), so I switched to path based
mounting, and so far I have not experienced the problem in exactly the
original form (although it only happened occasionally anyway, so
there's nothing conclusive here).

But I'm still having trouble with snapshot removal.  I'm using
rsnapshot's lvm integration: the utility creates a snapshot, mounts it,
does a rsync based backup of the snapshot, umounts the snapshot and
then removes it.  But rsnapshot keeps bailing, claiming that the
snapshot can't be removed.  When I try to remove it manually, I get the
"Can't remove open logical volume" error.  I generally find that after
waiting a few minutes and trying again, it works.  It isn't mounted
anymore, so why isn't it going away the first time(s)?
