I have been running 3.7.0-0.rc7.git1.2.van.main.knurd.kswap.4.fc18.i686.PAE a bit over 23 hours and kswapd has accumalated one minute 8 seconds of CPU time. I did several yum operations during that time and didn't see kswapd spike to 90+% CPU usage as I had seen in the past. With some kernels I wasn't reliably triggering the kswapd issue, so it may not be long enough to know for sure that the problem is fixed.
I also should note that when I tried 3.7.0-0.rc7.git3.2.fc19.i686.PAE I did see problems with kswapd hitting 90+% usage of a CPU.
