[Marvel] What would happen if a teleporter tried to teleport while holding on to Thor's hammer?

Mjolnir has been shown going through portals (though being held or thrown by Thor at the time) so it's entirely possible that it could be done.  Depending on the method of teleportation though, those like Nightcrawler definitely don't want to try.
