Wallframe unusuably slow at BLC #28

At Hackerman the menu, screensaver, and apps are reasonably snappy. At the BLC the same code is very slow to the point the menu cannot be used, and the screensaver and apps do not work.

For short periods of time, in particular if there is a single user, the system runs ok. But very quickly it stops working. In particular multiple users seem to make things seize up. At the same time the system stops working I have observed that the CPU usage will be pegged for the tracker, user manager, and screensaver, and very high for the infobar and other apps. I need to verify at hackerman how the cpu usage looks with multiple users. The problem may be a lot of overhead from ros topics that gets exposed on a slightly slower machine when they are more users. One test should be throttling tracker output and see how that changes the cpu usage.

One difference with hackerman is that the BLC wall is higher resolution. Perhaps that is exposing some problems with drawing graphics. The nvidia driver, X, and Qt versions should be compared against hackerman.

We should make sure all the modules are setup for optimized builds.
