// P11 M: THE SERVER HALF OF A SPLIT eglSwapInterval. The client's emit-table slot forwards the
// call as one control frame (ServerLoopTest.TheEmitTableSwapIntervalSlotCrossesAsOneDispatchedFrame,
// P10 B) and the server answers it with backend->SetEGLSwapInterval, whose base implementation
// calls the backend table's SetSwapInterval. Magma's slot was null until dev@c60639db, so the
// request was dropped there on every arm. Through the backend object, as the server calls it:
// the request has to land where the next renderer and Present read it. No renderer exists here,
// so nothing is rebuilt.
