Pegs CPU after exiting when displaying 3D graph

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run Arity
2. Show 3D graph (i.e. x/y)
3. Exit with back button

What is the expected output? What do you see instead?
I expect it to just exit and be gone. Instead, it exits, but the system
crawls (this is on a Nexus One; when it crawls, you KNOW something's wrong)
and a system monitor such as htop reports that arity is at ~90% CPU. After
killing arity's process, things return to normal.


What version of the product are you using? On what operating system?
Nexus One with CyanogenMod 5.0.4.1
