    Actually test6-pre* seems to, at least for files and processes.
    See linux/kernel/user.c

    I guess it would be trivial to use it for mlock too. Of course you still
    want a global limit too. Having a few pages mlockable per user per defalt
    would be very useful for cryptographic software that does not want its
    keys stored on the swap partition.
