Follow-up Comment #1:

Sounds easy enough to do, although a google search turns up a lot of questions
about the potential performance hit from doing this unconditionally. So while
it may help greatly for the case you have in mind, it may hurt the GUI in
general and everyone else who doesn't need this feature. I don't know, I
haven't tested it.

For reference, XInitThreads could be called directly, or, if we ever require
Qt >= 4.8 at some point (we currently work with >= 4.6), Qt now has an option
to initialize this for you:


QApplication::setAttribute(Qt::AA_X11InitThreads);


but again, only in Qt 4.8 or higher. This call must be done before
constructing the QApplication object.
