  Use the VM_ALLOC_INTERRUPT for the page requests when allocating memory
  for the bio for swapout write. It allows the page allocator to drain
  free page list deeper. As result, a deadlock where pageout deamon sleeps
  waiting for bio to be allocated for swapout is no more reproducable in
  Alan said that M_USE_RESERVE shall be ressurrected and used there, but
  until this is implemented, M_NOWAIT does exactly what is needed.
