What's this line for:

>+    if (nr_pages > target_pages)
>     {
>-        PERROR("Could not allocate memory.");
>-        goto error_out;
>+        pod_mode = 1;
>+        mem_flags |= XENMEMF_populate_on_demand;
>+        IPRINTF("I SHOULDN'T BE HERE !!\n");

It's not clear what this patch does to the PoD logic... does it still
need some work, or should I try harder to grok it?  Have you tested it
in PoD mode?
