+ * only one page long.
+ * data: The data segment follows next. We use current->end_text to
+ * current->brk to pick up all of the user variables, plus any memory
+ * that may have been sbrk'ed. No attempt is made to determine if a
+ * page is demand-zero or if a page is totally unused, we just cover
+ * the entire range. All of the addresses are rounded in such a way
+ * that an integral number of pages is written.
+ * stack: We need the stack information in order to get a meaningful
