+ *
+ * The circumstances that lead to a call to this function are very rare.
+ * Xlib must run out of IDs while trying to generate a request that wants
+ * multiple ID's, like the Multi-buffering CreateImageBuffers request.

+ * No rocket science in the implementation; just iterate over all

+ * that aren't in use. A more efficient algorithm could probably be
