Yesterday I gave my N900 a real hard beating - the swap went to 300 mb, the CPU was always or nearly always on 600 mhz with running media player, multiple browser windows, gpoder syncing, app manager installing aps, timer counting time and... nothing. Rock solid. The only difference was that I was not in tablet mode and gsm was on. But this might be a coincidence or just luck. Will test further with GSM on. Maybe the tblet mode app is the issue here.
