 uninstallation.

 After applying the patch, please activate the example plugin, deactivate
 it and then uninstall it.

 You will see that it does, in fact, work.


 > 1) register_uninstall_hook() would need to be run in global scope.

 I don't see what scope has to do with this.

 > 2) The callback would need to be in the same file as the call to
 register_uninstall_hook().

 Unlike with the uninstall.php method, the main plugin file is loaded
 before the hook is fired.

 So, as long as the plugin includes the file with the callback(s), it
 doesn't matter where they are.

 It's really not that different from register_deactivation_hook().
