Start by answering the question: "How can *any* process connect to 
another running process ...". Once you know how to do that, that may give 
us a hint how to do the same using Python.

I would expect that there needs to be some sort of OS-specific interface 
where you pass the process ID you care about to some OS function, and it 
will report the process state.

If your operating system doesn't support that, the only other option that 
I know of is if the application you are interested in *itself* provides 
an interface to question it while it is running. On Linux, that might 
including sending it a signal (see the signal.py library) or it might 
include some form of interprocess communication. But whatever it is, it 
will likely be application specific.

So if the OS doesn't support this, and the process you are interested in 
doesn't support this, then it likely can't be done.

Sorry, I don't understand this.
