    x11: XMaxRequestSize returns 4-byte units
    
    XMaxRequestSize/XMaxExtendedRequestSize are documented to return
    the maximum size in 4-byte units, whereas we are comparing this
    to byte lenghts. We can afford 4x the data here.
    
    Since I don't know the payload size of the XChangeProperty request,
    be generous and allot 400 bytes for it, we have some to spare.
