+ *
+ * The direct read/write stuff was iimplemented first, and I followed it by
+ * generic read/write when memory mapping was implemented. During the
+ * transition both options worked. Things have now moved on and not
+ * defining USE_GENERIC_RW is broken, with no real motivation to fix it.
+ *
+ * Ie. You should always define USE_GENERIC_RW.
+ *
+ * This comes up every couple of months on the list. I guess I should pull
+ * it out.

-      Use generic_read/generic_write for reading/writing files. This
