Does this mean generally I can't run an external command with output into a buffer (or buffer region)?

Vim doesn't do concurrency either, so that wouldn't be a regression.

Yes, but it does single thread scheduling to compensate (as does emacs) while Yi doesn't which means implementing quickfix (and other modes) isn't too viable without halting the whole editor.

You can, it will just hang the editor while it happens. An easy test is having Yi call something like ‘sleep 5; echo foo’. It should be easy to see why it's a big problem at the moment. Personally I stumbled upon it when trying to implement myself an IRC client inside of Yi but there are many use cases. Anyway, I feel that we're getting a bit off-topic here. If you're interested in helping out with implementing the concurrency stuff, we'd love to have you: pop into #yi, look around the issue tracker and maybe even post to the Yi mailing list. -- Mateusz K.
