Subject: when opening a msg with a 4 MB attachment emacs (master) consumes 6.4
 GB of RAM
Date: Sat, 01 Dec 2018 10:11:46 +0100

Hi 

I tried to open a msg which contained an attachment of 3.9 MB, my system
with 8 GB got almost frozen and 
#!/usr/bin/python

# -*- coding: utf-8 -*-
import re
import sys

from ps_mem import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Told me 
rivate  +   Shared  =  RAM used       Program

 6.6 GiB + 343.5 KiB =   6.6 GiB       emacs-27.0.50

This cannot be good.
