Fix for bug 75840: syncshadowdb -syncall now properly shuts down Bugzilla during the sync process so mysql doesn't get overloaded while the tables are locked.  This patch also adds some funtionality to the script to allow you to specify an alternate temp directory on the command line, in case you have a large database and need it made to a different filesystem for space reasons.
