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
