    Sounds like Staircase's interactive mode switch, except this actually
    requires writing additional code.

    The per-user system would also be nice for servers, provided there are
    CPU/disc IO/swapper/... quotas or priorities at least.

    All in all, I'd hate to see mldonkey eating 1/3 of CPU time, just
    because it runs as another user.
