Is there a ::destroy() method on the EShell object (like GtkWidgets)?
Perhaps it would be better to unregister there rather than in an idle
cb? My concern is that in the idle cb, there may still be a race? Even
if not, tho, I feel it would be cleaner to unregister in a ::destroy()
if that's a possibility.
