You are assuming that these old processes are only answering NOOPs. What 
if they are checking every folder for mail every 5 minutes? every 
minute? every 30 seconds? (yes, I've seen that).

So now if we assume that a process is costing me resources that I wish 
to recover, what is the right way to terminate it?
