setting this to urgent, to see if addressing it will improve overall UI 
stability any. Its not on its own a serious issue, so priority can be dropped 
if fixing doesn't help the effort.
Comment 2 Ian Springer 2011-08-16 19:47:49 UTC 
This is because there are two action buttons on the groups list views which extend AuthorizedTableAction - the Delete button and the New button. Each AuthorizedTableAction will make an RPC call to retrieve the global permissions. We could optimize this so that a single call to load the global perms is made by the Table itself and all AuthorizedTableActions share the results, but since getExplicitGlobalPermissions is a very inexpensive call and there will never be more than a handful of AuthorizedTableActions for a given Table, it's really not worth the effort.
