This purpose aligns well with those of the ArmoredCatalog proposal as well..

This should not happen.  :-(

I'm really disappointed that the bloat and memory consumption issues are
still plaguing the ZCatalog.  At one point, I really thought we had it
pretty much licked.  I suppose this was naive.

I apologize for this.  We have a fairly formalized process for handling
feature-ish collector issues, and this hasn't come round on the guitar.  I'm
beyond disappointed that people are still having unacceptable bloat, enough
that something like this patch needed to be submitted.  It's disheartening.
