I wonder why gnome-panel would be touching /autohome/share.

I guess what I wonder also about all of this is that isn't there some
period of "idleness" required before anything is unmounted?  Is that the
60s that I am seeing?  If I increase that to a period longer than the
periodic access by gnome-panel should that not stop the trashing of the
mount?
