Does Qt5 take advantage of XCB's ability to send a pile of requests and
then get back a pile of responses, without waiting for a round trip each
time like Xlib does?  In particular, does it do so for the pile of
requests needed at startup time?  If so, perhaps you could time
application startup, both locally and over a high-latency connection.
