I've found that duct tape applied inside the pants (or shirt) so as to put the tab of the tear snugly back into position will yield far more than two or three more wearings.
The Duct Tape Folks should put out a version with a softer backing to make such fixes more comfortable, especially for those annoying tears around one's pants crotch.
