------------------------------------------------------------------
Fixed (estimated range based on the arrayKeyBy benchmark). It probably is
2d67ee0..60b3f2f. Previously I copied wrong hash because of some bug in the web
UI? [This url|http://codespeed.dak8s.net:8000/changes/?rev=2d67ee0&exe=1&env=2]
shows the benchmarks results for 2d67ee0 commit, but the wrong hash is
displayed in the ui (at least for me).
A second suspect could be commit: c41e0879160e4e3088abe6496d3827d479d802df, but
that's a bit unlikely (mailbox changes shouldn't show up in those benchmarks,
but I might be wrong)
