I use a token file. I write a token file to the stacks folder with the
time the app is started, the app update this file every 5 seconds, when
the app quits, it deletes the file, when it launches it check for the
presence of the token, if it exists, it check to see if it is more than
5 secs old (this mean that the app force quited an left a stray file),
if it is less then 5 secs old, we have a running instance.
