I changed the return type. That meant the caller now had to deal with
3 possible values instead of two.  There is a no way a refactor can
handle that.  It is called Change Signature in IntelliJ. It is great
for swapping parms, or changing a type, or adding a new parm. When you
add a new parm, you still have to visit all the invocations to touch
up if the default value does not apply.

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
