[macos] memory use up to 1gb

[Jean-Christophe Helary]

I'm starting emacs with 30 buffers (of which 28 are files), with no running 
processes and the memory footprint is about 150 mb.

After a few days of working with the buffers (mostly text editing, org-mode 
use, packages updates, etc.) I end up with more than 1gb of memory footprint.

Is that an anomaly ? Does that correspond to undo information and other things 
like that ? If that's an anomaly, how do I debug that (it seems to take some 
time to reach that value) or how do I avoid that phenomenon ?

I'm using the regularly updated "vanilla" master branche (simple "make install" 
on macos 10.14.6).
