There was a problem hiding this comment.
Was going to suggest you might consider adopting the same sort of logic the importer uses to reuse box temps. But currently does not seem to be not worth the trouble.

A: they are quite unique in that they're multi-use, multi-def, and both uses and defs can appear in arbitrary places.
Diffs.
