In theory, it’s supposed to be ignored, but who knows.

Gnulib says (info "(gnulib) mmap"):

   * To get anonymous memory, on some platforms, you can use the flags
     `MAP_ANONYMOUS | MAP_PRIVATE' and `-1' instead of a file
     descriptor; on others you have to use a read-only file descriptor
     of `/dev/zero'.

Perhaps worth a try, too.

Thanks,
Ludo’.
