If you use Windows, then after upgrading to the latest in svn (or the next nightly build), please pay extra attention to whether DrScheme or other MrEd-based programs consume too much CPU.
We've seen some problems with DrScheme maxing out a CPU when it should be idle. The problems happened especially with blocking reads on network sockets, but similar problems could happen with any GUI application. The latest changes fix the problem on my machine, but this fact of the system is difficult to test.
