i'm almost positive that, like others have suggested, the recurring programs on the applications list in advanced task manager are not the actual executables, just their prefetch parameters. if you click on the processes tab, you'll see that some of the apps are running in foreground, some in background and some are idle. the idle ones aren't using any resources other than keeping their temp files in ram. the phone experiences no slowdown whatsoever when these processes are open. it only slows down somewhat when you start to multitask with running applications, like playing music and browsing the web simultaneously. the system is also smart enough to start killing cetain less essential processes when more cpu-heavy apps demand the resources. all in all, i highly doubt that repeatedly killing these reoccuring tasks will really improve the phone's performance. infact, i would guess that the phone will probably experience a few seconds of slowdown after every flush, because the system will rush to prefetch the killed apps again, taking up cpu cycles. as of now, i've set up an ignore list in advanced task manager, consisting of the following:

-motorola.hiddenmenu
-google talk storage
-alarm clock
-calendar
-corporate calendar
-settings
-messaging

the other apps don't seem to reoccur as insistently as these, which makes me believe they are non-essential but sometimes the system bumps up their priority depending on their use frequency (say if you use the camera, or the picture viewer which is part of the camera app, often, it will bump up the camera app on the prefetch priority list and you'll see it start to reoccur more often). i don't care that much how quickly the picture viewer or the browser or the market app, etc. start up, so when i see them pop up on the prefetch list, i choose to kill them.

of course i'm just guessing, but this makes more sense to me than a bug in the system that makes apps start up randomly by themselves. i think we would see major lag after a few hours of every reboot if that were the case.
