- TSVN choked repeatedly when attempting to merge ~9000 revs into the branch (tried 3 times on 2 different computers) - If someone wants to delete aicom-network-fixes, they are welcome to - Lesson learned: Letting a branch get thousands of revs out of date is a horrible idea svn path=/branches/aicom-network-branch/; revision=44353
