.SH DESCRIPTION
While a client using Xlib/XCB can issue requests and handle their replies or
errors with either Xlib or XCB, only one can own and handle the event queue.
By default, Xlib must own the event queue, for compatibility with legacy Xlib
clients.  Clients can call \fIXSetEventQueueOwner\fP immediately after
\fIXOpenDisplay\fP to let XCB own the event queue instead.  Clients may not
call \fIXSetEventQueueOwner\fP at any other time, as this will potentially
lose responses.
