Made the relaunching process much snazzier, courtesy of Cedric Luthi. Now we use a separate program to kill the host app and to watch for when it is actually closed to launch its successor. Please let me know if you have any problems with this.K |

by David Smith
At Andy's suggestion, don't bother with overly paranoid fallback behavior. If we can't copy to NSTemporaryDirectory(), something is very very wrong and we should bail. This greatly simplifies some things and lets me clean up the copy of relaunch once it's done. :) |
