One thing to think about: the VPN gets torn down when you loose your
connection.  So does your unmount operation still work OK (and not block
until a TCP timeout or something) when the connection is already torn
down and you no longer have a route through the VPN?  This will _always_
be the case, even if there is eventually an advisory VPN termination
signal.  There will always be the case of an interrupted connection.
