     * We sort the colormap by closeness and try to allocate the color

     * Either the colormap must have changed (since the last close color
     * allocation or possibly while we were sorting the colormap), or the
     * color is allocated as Read/Write by some other client. (Note: X
     * _should_ allow clients to check if a particular color is Read/Write,
     * but it doesn't! :-( ). We cannot determine which of these scenarios
     * occurred, so we try the next closest color, and so on, until no more
     * colors are within closeness of the target. If we knew that the
     * colormap had changed, we could skip this sequence.
     *
     * If _none_ of the colors within closeness of the target can be allocated,
     * then we can finally be pretty sure that the colormap has actually
     * changed. In this case we try to allocate the original color (again),
     * then try the closecolor stuff (again)...
     *
     * In theory it would be possible for an infinite loop to occur if another
     * process kept changing the colormap every time we sorted it, so we set
     * a maximum on the number of iterations. After this many tries, we use
     * XGrabServer() to ensure that the colormap remains unchanged.
     *
     * This approach gives particularly bad worst case performance - as many as
     * <MaximumIterations> colormap reads and sorts may be needed, and as
     * many as <MaximumIterations> * <ColormapSize> attempted allocations
     * may fail. On an 8-bit system, this means as many as 3 colormap reads,
     * 3 sorts and 768 failed allocations per execution of this code!
     * Luckily, my experiments show that in general use in a typical 8-bit
     * color environment only about 1 in every 10000 allocations fails to
     * succeed in the fastest possible time. So virtually every time what
     * actually happens is a single sort followed by a successful allocate.
     * The very first allocation also costs a colormap read, but no further
     * reads are usually necessary.
