+ * 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
