+ * almost always be the number requested.
+ *
+ * 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
+ * possible IDs for the given client and pick the first count IDs
+ * that aren't in use. A more efficient algorithm could probably be
