It's definitely "ok".  The server and XCB have a bunch of
machinery that makes it pretty easy for you not to do that,
and just have each thread more-or-less pretend it owns the
connection, but if you want to open a connection per window
group it certainly doesn't hurt anything.  The "less" is
mostly what you described earlier; each event will be
consumed by exactly one thread.  But note that with XCB
multiple threads can be making requests and receiving
replies over a shared connection, and it will all just work.
