As he said, if you run out of them, you cannot start any further X11
application.

Show X11 windows, though apparently not each X11 window has its own
client connection. QApplication creates an X11 connection, but maybe
there are circumstances where a new X11 window also gets a new X11
connection.

Apparently 255 according to what link google shows as first match for
the error message.
