While the research seems to be quite thorough, the following statement:
"Error is caused because Cocoa currently doesn't run through base level
NSApplication.run and thus appropriate ._isrunning flag is not set "

contradicts Apple's documentation (
https://developer.apple.com/documentation/appkit/nsapplication?language=objc
)

"...Methods to Override
...
Override run if you want the app to manage the main event loop differently
than it does by default. (This a critical and complex task, however, that
you should only attempt with good reason.)"

If the first statement is true, then run cannot and should not be overriden
at all.

thanks,
Dmitry
