If new code is going to be written to implement (or reimplement) debugging facilities I would strongly advocate that enhancing DTrace to work on more of our architectures would be a more productive use of that time. > - I'm not sure you want to have dtrace running on a production server.

The probes are basically zero-cost (static probes, where they are explicitly placed in the source code, are __predict_false(); dynamic probes as would likely be use here are binary-patched into place).
