Thrashing thrashing

Ah, we have so many ways of distracting ourselves. Most of us do, anyway.
I quite like this (though a brain is not a computer!)

It is the same with a computer cache: there will be a hierarchy – from super-fast memory in the microprocessor itself all the way down to a hard drive (slow) and offsite backup (very slow). To speed things up, the computer will copy the data it needs for the current task into a fast cache. If the task needs to be switched too often, the machine will spend all its time copying data for one task into the cache, only to switch tasks, wipe the cache and fill it with something new. At the limit, nothing will be achieved. [Peter] Denning described this regrettable state of affairs as “thrashing.”

In other word, what we all know – one thing at a fucking time, if you can, room of one’s own etc.
