Root Running least apps possible

[bradm23]

I'm trying to figure out a way using a task killer to have all of my unused apps close when my phone sleeps. Anyone do something like this and what program and settings do you use?

If you're on 2.2 just let android handle it. On 2.1 I used System Panel. Open it, close all, and exit. Or use the homescreen widget to end all.
