TOP for Android

Frontend for android top. Newer android versions prevent top from showing anything but itself.

Root is currently used only for kill, so it does not help either.

from http://en.wikipedia.org/wiki/Top_%28software%29:

top is a task manager program found in many Unix-like operating systems. It produces an ordered list of running processes selected by user-specified criteria, and updates it periodically. Default ordering by CPU usage, and only the top CPU consumers shown (hence the name). top shows how much processing power and memory are being used, as well as other information about the running processes. Some versions of top allow extensive customization of the display, such as choice of columns or sorting method.

You can also kill any procces on rooted devices. App does simple su -c kill -9 pid. This kills the crab.
