Good question, I've missed that!

Sadly I don't find it possible. The main thread of QEMU has to run the glib
event loop so it cannot block on SDL_WaitEvent().

Ideally SDL should provide an API to get a pollable fd (or a set of) to allow
such types of integration, not much can be done from QEMU side in its current
form.
