commit dec51e14bf347c940e966d88fee772b181560e4d
Author: srowen <srowen at 59b500cc-1b3d-0410-9834-0bbf25fbcc57>
Date: Thu Mar 25 11:42:08 2010 +0000
Avoid RSS-14 false positive issue, which temporarily hurts its scanning a lot, but will work more later. Readjust unit test pass counts, which seem to have drifted. The change is net neutral in any event.
