There is no real problem with LibreLogo AFAIK, except that it's kind of a
non-feature which even caused security problems due its Python implementation
(I have no idea how someone thought this might be a sensible feature for
LO...). But this is a good and easy test, which is hard to find for the whole
system event loop integration, let alone unit tests.

The event loop will always be very system specific. But the LO scheduler and
the processing of LO internal events (AKA UserEvent) is definitely a good idea
to further unify (OTOH every time I touched this low level stuff, I broke
things, so I'm not really eager; nobody else even wants to touch it).

I failed to parse this. This is nothing I will / can do in my free time, if
that's what "economics" refer to. The city of Munich "sponsored" a lot of this,
so even if it didn't directly help any particular of their problem, I could
work on it to tackle some underlying problems instead of somehow working around
them. It also didn't help, that the VCL plugins did stuff completely or
slightly different without any explanation... "Why?" is the most common thought
when reading LO code (next to wtf, obviously), not what; at least for me.
