Using a "machine-name + PID" will absolutely work, because:
1) If the machine-name is the local machine, you can check the PID and
if the PID is not gnucash, you know it was an unclean exist.
2) If the machine-name is the local machine, you can check the PID and
if the PID IS gnucash, you know there is another running instance.
3) If the machine-name is NOT the local machine, then you cannot
differentiate what's going on and should ask. Most likely it IS open,
but there's no good way to tell.
The good news is that #1 and #2 ARE the most common use-cases today, so
we should implement that.
