Are you sure the non-spatial keybinding doesn't work? You have to
release all keys before starting it and there must be a focused window.
Please, can you investigate?

It listen for event(1) and proceed(2) them when there is some in the event
queue. So clfswm is sequential and need only one thread/loop.
But there is some optimizing functions to compress mouse motion events
for example.

I have had a look at XCB(3) but I haven't gone in this direction for
now.
