I remember a situation around 1980 where my boss became very angry with IBM, when they decided to sell memory in chunks of one full 1 MB, while we only needed 0.5MB extention for the next year. I think we had 3 MB or so then. I then wrote a 'blocking' program, that blocked the unneeded memory, in order not to spoil the users with too good performing systems.
