I explained poorly. I ran into issues with updating jemalloc as part of a software update. While debugging the issue I disabled jemalloc (unsetting the ld_preload) and noticied a sharp difference in how much memory ruby had allocated. I guess _pre_allocating is incorrect and a better explanation is _not releasing it_. Thanks for rebutting my argument and giving me the opportunity to elaborate.
