[erlang-questions] very long init:stop() and +P emulator flag

[Vyacheslav Levytskyy]

That's true, I don't need 134217727 processes to be running, but it is 
not substantial. It is just counter intuitive for me to have a beam 
process with only kernel+stdlib that must take 5-10 minutes to shutdown.

If you are right and this indeed happens because of 1,5Gb allocated (btw 
does this mean that each of 134217727 potential processes is 
pre-created?), I would say that setting an upper bound of something I 
don't expect immediate actions. Out of curiosity, I wonder what should 
be cleaned up in the system immediately after the clean boot, and did 
this behaviour exist earlier or was introduced recently (maybe as an 
optimization) with Erlang/OTP 19 or 20?
