ChangeProperty is a little bit of a pain because properties can have
just about any type. Arg 8 was a void* because of this, until I tried a
few days ago to fix a -pedantic warning in XCB. It was using
sizeof(void), so I changed the type to char*. I guess what I should have
done was special-case void to not generate the sizeof. That fix is in
xcb-proto and xcb now, though I haven't tested it against the demos.

That's part of XCB's internal list API that definitely shouldn't be made
externally visible, because it's not type-safe. There's no public API
for what main.c is doing, because apps aren't supposed to touch the
pending replies queue.

Either that test should be removed from that app; debugging code should
be added to XCB that reports statistics like this; or main.c should
#include <X11/XCB/xcbint.h>. Any thoughts?
