Well, the problem hasn't reoccurred with that patch applied. I'll leave
it running overnight as quite often one or two windows have disappeared
by the morning. The machine still becomes unresponsive whilst the dd is
happening though (eg tab completion takes an age, loading programs takes
an age, typing into windows doesn't echo). Is that meant to happen? FWIW
whilst the dd was happening I did a vmstat -a 1:

I restarted the dd about here so I guess the file was deleted somehow
freeing up memory.
