Excuse me for going on about swapping. I am using the same thread so anyone who has killed it won't be bothered. I was running firefox and had plenty of tabs open, but reasoned that if these are swapped out (that is to say the memory used by them is swapped out) then it won't matter. But the system ground to a halt. What puzzles me is how long this goes on for. I am not sure how long it would take to swap the whole 1.5 G of RAM out but it seems to be stuck for much longer than that. In order to get some idea of what's happening I ran vmstat (on my reniced -19 console) and found that it wasn't actually swapping, the activity was BI and BO, which I think is to do with buffers? The page I went to in firefox was maps.google.co.uk. Eventually firefox came up with a tiny little window with nothing in it. Then some time after that a message appeared saying "something is slowing down your browser, what would you like to do?" and there were two very flat buttons (i.e. small vertical size, long horizontal size) and nothing written in them. The system did eventually stabilize without me doing anything. I think something is going wrong, but I am not sure what. I have a local installation of Mozilla Firefox 74.0, i.e. I downloaded and unpacked into /usr/local.
