arsd users: weigh in on proposed breaking change

[Greggor]

I use some of your stuff so I'll chime in. I don't automatically 
pull in files and so the updates to modules is done by hand in my 
case, so you adding a few dependencies is not a problem.

But I do not pull in the full arsd repo & I'd hate to see that to 
become a requirement. In general I love the "its just a few files 
you can add" to dependency management, but I don't mind it 
becoming a couple of files.

As for event loop stuff, there is a golden rule in my eyes, as 
long as there is a way to own the loop, just call a poll/dispatch 
function and I can still use the thread, there should be no issue 
with it.

The moment that is not the case that's when that type of stuff 
turns painful :^)
