 I have a multisite installation (4.0.1) with revolution slider plugin
 installed. This plugin has an uninstall.php file (that deletes revslider's
 database tables) which should be called on plugin removal
 (http://codex.wordpress.org/Function_Reference/register_uninstall_hook).
 It does not call the register_uninstall_hook function.

 The problem is: when i delete a site from the network dashboard, revslider
 databases are kept, meaning that uninstall.php was not called. I'm not
 sure this issue can be addressed and i did not tried with a plugin using
 the register_uninstall_hook (which is the best method if i did understand
 the documentation correctly).

 Questions: Can this problem be fixed ? Is the register_uninstall_hook
 called when deleting a site in multisite configuration ?
