[monitor_fdpass.c]
     msg_controllen has to be CMSG_SPACE so that the kernel can account for
     each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len).  This
     works now that kernel fd passing has been fixed to accept a bit of
     sloppiness because of this ABI repair.
     lots of discussion with kettenis
