That number is not that relevant to the intent of memory-limit, and on 
my platform (Fedora 24 x86-64) returning 0 is a better approximation. 
That being said, we can add some help along those lines, in the attached 
patch, slightly modified from the original to suggest (alist-get 'vsize 
(process-attributes (emacs-pid))) for users who prefer the virtual 
memory size.
