Without having checked the code, I suppose it's due to starting with
less apps (modules) and similar settings. From what I recall, I think
it used to start the VM with args like "-mode minimal" and maybe other
switches, but I don't remember it all.

The increase in startup time after R13 is unfortunate and asking for
someone to profile and check for possible improvements. Maybe there's
also a need for an erlc-like escript startup mode that could try to
delay stuff.

Anyway, Loic, this is off-topic, so we should either use a separate
thread or not pollute the pkg mgr thread.
