I am far too well aware of this ;P The reason why I'm not even
mentioning this as a possibility is because it is a terrible thing to do
and requires a lot of juggling to behave more or less like you'd want
it. Even today I have my emacs freeze up when I run cabal repl inside of
it for the first time.

Also as I mentioned, we have no means to periodically run things, which
means we can't periodically query our subprocess. There is no mechanism
for such scheduling and while doing it in a single thread like emacs and
vim do is *a* way to do it, you yourself point out that it's sub-par.

So yeah, I'm not even starting to consider that option, I don't want to
end up with yet another editor that doesn't do actual concurrency.
