Wanted to let other users know. Since installing, I've replicated the following problem easily. This update uses between 94-98.7% of the CPU when you reboot. I noticed some incredible lags in my MBP and an extreme and otherwise not usual heating. When going into the activity monitor the usage for the airport is sky high. Shutting off the airport and just turning it back on seems to stop this memory leak and over heating. Until you reboot the problem does not resurface.
