Description
To answer my own question...it's almost entirely due to make_typealias in base/show.jl. https://github.com/JuliaLang/julia/pull/36107. I think there was discussion of caching its results at some point, but I can't find the issue.

Research direction
Read base/show.jl, focusing on make_typealias, and inspect Julia PR #36107. Reproduce the long-method-body slowdown in Cthulhu.jl and determine whether caching those results is an actionable fix; the issue is done only when a concrete change and validation are defined.
