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
