Using eventsloop only as source of events

[Shookbelf]

Hey,

I want to use eventsloop only as a source of events for my actual main loop to receive. For this, I run it in another thread. Polling is not an acceptable solution.

Now I have the same problem as specified in #239: Window methods like get_inner_size() are blocking when the eventsloop is asleep. Could you clarify if this usage is supported? If it isn't, why would Window be Send + Sync?

Hey, sorry for the delay. I honestly have no idea whether or not that usage is "officially" supported, since those who came before me didn't document extensively. I will say that I encounter this problem in my own app, and that it's super annoying. It works fine on Windows (I'm not sure about on macOS, since deficiencies in glutin currently prevent sending a Window to another thread there).

I'll say two things:

• Xlib's multi-threading support is notoriously shoddy, so I can't make any promises.
• I'm waiting to try to fix this until during the backend rewrite that will be required by whatever consensus we ultimately reach in API Change Proposal: Events Loop 2.0 #459.

@vberger does #842 fix this?

I don't know enough about the x11 inner workings to answer that tbh.
