I don’t genuinely think that using DTrace probes on a kernel coredump would work today, and even if it did, I don’t think it would make sense (DTrace -> Dynamic Trace). What gjb/jhb are discussing is post-mortem analysis of a coredump (netstat uses sysctl(3) to query the routing socket on live kernels).
