2# VM defaults must be installed before Erlang starts in every launch mode.
3# The daemon waits on the network and its kernels, so two schedulers that never
4# spin carry it. Mostly-empty heap and binary carriers are abandoned (acul) and
5# their free pages handed back (acful), and freed segments are not cached
6# (MMmcs), so memory a busy turn took goes back once it is over.

8# Application startup can log before Gleam main runs. Keep diagnostics off the
9# helpers' JSON stdout, including when a shipment starts dependencies first.
