[HACKERS] DTrace probes.

Howdy,

I just saw Robert Lor's patch w.r.t. dtrace probes. It looks very
similar in what we've done. We run a nice set of probes in production
here that allow us to track the details of checkpointing and statement
execution. I've given a few presentations around these probes and
have had very positive feedback. They've been available for a while
now, but I never got around to sending them to the list:

Documentation is in wiki format, but I'd be happy to convert it to
something else:

Best regards,

Theo
