"deadtime" only works if the number of open files from that client
approaches zero. It cannot be guaranteed in a windows client world,
however: one explorer hickup and the file stays open for samba. Take a look
at smbstatus at evening when all clients have disconnected. Most of the
time there are still some leftover locks.

A fake share with a root preexec command "kill this client's smbd session"
would be useful.

There is the auto-mounting facility, which reads /etc/auto.master and files
that that points for a list of mountable locations. That's normally used for
NFS mounting, but I assume it can work for SMB.

Alternatively, you could set up a cron job in /etc/cron.d/ to probe the
mount point and see if its held open by anything with the "fuser -m"
command, although I've never tried that with SMB mounts, and then unmount it
if it's not active.

The cron job might be easier.

Ouch. That's nasty.
