Comment 74 for bug 1672297

I managed to build and install a patched gjs last night thanks to a helpful hint from a fellow user (ie to use debuild -us -uc -b to build it instead of make and make install).

Initially, gnome-shell was using around 170 MB according to gnome-system-monitor (atop says consistently says it is using around 100 MB more). It stayed that way until the next morning when something made it jump to 250 MB, and an hour or so later it jumped to 350 MB (it's hard to tell if it jumped all at once or slowly increased, because I think there's a bug in gnome-system-monitor that makes it stop auto-refreshing until you click on its window - when I clicked on gnome-system-monitor, gnome-shell's displayed usage jumped 100 MB each time).

Usage stayed at around 350 MB for the morning and most of the afternoon. Eventually, I restarted gnome-shell with ALT-F2 and 'r' and usage dropped immediately to 120 MB. It stayed there for about half an hour until it suddenly jumped to 170 MB, and it has been sitting on that for the last two hours.

gnome-shell with an _unpatched_ gjs on my system will go to 450 MB or more in less than an hour, so I think there's a definite improvement with the patch, but there are still some big leaks there.
