Passing array offsets sounds brittle to me.

It would screw up any attempts to post-process the plans. Later
enhancements seem certain to break that scheme.

It also assumes that all actors have access to a single memory structure
that describes everything.

Hopefully we are working on a parallel query system that will work
intranode as well as across nodes, so access to memory should not be
assumed.
