I added a few nodes (maybe two?), _and_ added some call-outs to existing nodes to
follow their children down. This stuff can be bracketed with debugging #ifdef's; it
was very helpful for me when debugging but it isn't good if they are adding
unnecessary limitations on sizes. The additional nodes I added are a "don't care";
it's the additional printing of child nodes (fields of existing structures) which
is loading things down.

I am not absolutely certain that we are talking about the same thing, so should
confirm that it is the same routines which are causing trouble; this is the same
printing/formatting code used for "explain"??

I'd be happy to help clean them up, but I think you should help too; as I recall we
were both mucking around there about the same time ;)
