--- Comment #3 from Peter Holm <pho at FreeBSD.org> ---
I have tested the patch and this indeed removes the panic.

Out of curiosity I added a "failed allocation" counter:

+       if (m == NULL) {
   /*
    * Not allocatable, give up.
    */
   mtx_unlock(&vm_page_queue_free_mtx);
+  atomic_add_int(&pho, 1);
   atomic_add_int(&vm_pageout_deficit,

which reached
pho = 100479984
during this test scenario.
