Just open a terminal before doing the mount.
Become root in the terminal.
Perform the mount.
In the terminal a "netstat --tcp --program" will tell you what process
is opening all the files; likely this will just be the GVFS worker.

But will lsof work on a GVFS CIFS mount?  It doesn't look like it works
on a WebDAV mount.

If you run "gvfs-mount --monitor" in a terminal does it display
anything?

Most of the time GVFS mounts are actually mounts
to /run/user/{username}/gvfs/{mount-url}.
