Subject: [PATCH] Fix race condition which can happen with multiple concurrent
 "launch"es - can end up with duplicate ToePools like before r7268, probably
 other problems * CrawlJob.java     launch() - synchronize this method - sort
 of a blunt fix but probably safest and shouldn't affect performance
