In a non-Pulp reproducer that merely calls parses the metadata with createrepo_c using the same code as Pulp RPM, it's clear that for some reason in this case there is a pathological behavior with the custom hybrid iterative parser.

The traditional "all at once" parsing peaks at 900mb, the new iterative parser peaks around 600mb, but our custom parser blows through the 15.5gb available on my VM and triggers the OOM killer.
