Original report by Ronald Oussoren (Bitbucket: ronaldoussoren, GitHub: ronaldoussoren).

3.3 (or even 3.4?) has option to pick a process model, use the prefork or spawn model (maybe auto configure when a dependency on m.p. is detected?)
other versions don't, and you have to fully initialize before doing anything GUI related (if it works at all, with some luck you'll have to have a separate daemon process)
check if freeze support is needed with py2app.

Python 3.8 and later already do the right thing w.r.t. MP models, and work with py2app (see #358)
