No problem- but that's also why I was thinking we should just wrap
end_heap_rewrite() in a context as well, otherwise the next person who
comes along to add a bit of code here may end up making the same
mistake.  Is there something you're concerned about there?

I have no problem *also* doing the pfree() to address the concern about
the transient memory usage being more than we'd like.
