You'll need to script this yourself by issuing removing the share
entry from smb.conf and using smbcontrol to close client connections
to that share and reload the config file.

Samba doesn't have logic to hook into your specific UNIX's method
of notifying dismounts (if it even has one).

Also, it's not a security hazard, as the admin - don't do that :-).
