Ensure that _XReadEvents always leaves an event in the queue on return
XNextEvent assumes that the event queue will be non-empty on return from
_XReadEvents, but with multiple event readers running, the previous change
could leave the queue empty on return from process_responses. Re-invoke
process_responses until the queue is non-empty.
