Interesting question & answer about "kill -9 <PID>"
that came up in the Android newsgroup just now

(1) Here is an example of the "kill -9 <PID>" shortcut in action:

(2) I have to wonder why anyone would kill with anything else but -9!

(3) I always kill without '-9' first.
A kill 9 kills but resources can be left hanging, used, and thus,
not possible to reclaim by other processes. Sometimes you have to
reboot to recover.
It is better to try a default kill signal, which basically tells
the application to quit, so it has a chance to close files
and return other resources it may have grabbed.
Only when it fails, as a last resource, use a 9.
