    I have a dummy question on /debug/trace: is it possible to
    - use 2+ tracers concurrently?
    - run a system script that makes use of a tracer,
    without disturbing the sysadmin's tracer activities?
    - access 1 tracer concurrently from many threads,
    with different filter etc. options?

    If not currently, will private mounts be a viable solution?

    Thanks,
    Fengguang
