Yes, and so I can do things like development, with IDEs and emulators
that consume additional GBs of RAM, while leaving my usual applications
running.

I understand all this, at least in general terms.

As I mentioned (briefly) in my original post, yes, I experience concrete
problems: the system either grinds to a halt or becomes unresponsive,
or hits swap and becomes intolerably slow.
Since upgrading to 16 GB a couple of days ago, I haven't had problems

GB ;/
