You could use ps(1). Inside the shell, you could run:

   $ ps -q $$ -o comm,rss,vsize

zsh              9640  13568

The 'ps' above -- different terminal, restart shell, but only twomentions of zsh, vs. four in the other terminal, most perplexing. But atleast the VSZ is the same. And if that's 13,566K, that's believable. So that's loaded, all in, functions and all? Then that's my number.
