Define "all tasks". Killing every single process will make your N900 reboot. So now take your time to make a list of processes that should not be killed. Then you can easily write a script to kill all pids not in your list (plus the name to pid mapping).
One way this might work would be to run as a daemon. It would be able to detect when the system has fully booted so it can recognise the baseline state. As each application, and its supporting services, initialises these would be logged so when shut-all is actioed it wouldn't kill off core system services.
...thinking aloud
Plus leave the RAM management to the kernel. He knows it better than you.

If OP got problems with multitasking, he should first find culprit, instead of developing ways of "killing"
@Jedi. Thanks for this script. I'm not a real whizz with on such matters, so please would you explain
- why does it require BASH?
- is there a way to convert it to be used with the standard shell?
If you've evolved your script over time, it'd be good to see the most recent edition.
There's also this - killing them all and being able to restart them all as well. This post is in the same thread as your

No, I'm using bash. The commands I posted work on bash, dash, csh and tcsh and I didn't even think about it that busybox might not support such basic things.

but when i used the command @sulu gave
Code:
ps ux
so "Close all tasks" should include all those apps too...
@jedi
thanks for the script... is your script killing the unseeable apps i mentioned above...

I haven't worked with the internals of this part of Maemo 5 so I don't know the exact details or why maemo-invoker doesn't exit before the application has quit. In any case, I wouldn't worry about those processes too much as they share most of their memory with the other instances of maemo-{invoker,launcher}. You can read a bit more about this at http://maemo.org/intro/platform/ .

Code:1856 user 3932 S /usr/bin/image-viewer 1857 user 38232 S /usr/bin/image-viewer 8497 user 3932 S /usr/bin/modest 8498 user 69124 S /usr/bin/modest 8724 user 3932 S /usr/bin/osso-addressbook 8725 user 32408 S /usr/bin/osso-addressbook 8870 user 3932 S /usr/bin/rtcom-messaging-ui 8871 user 34768 S /usr/bin/rtcom-messaging-ui 10781 user 3932 S /usr/bin/osso-xterm 10782 user 39376 S /usr/bin/osso-xterm
For example, if you take a closer look at processes 10781 and 10782 you'll notice that 10781 is an instance of maemo-invoker ("ls -l /proc/10781/exe") and 10782 is an instance of maemo-launcher. If you further look at 10782, you'll notice that its parent is maemo-launcher ("grep PPid /proc/10782/status" or "ps aux | grep $(grep PPid /proc/10782/status | awk '{print $2}')"). Once created, process 10782 is replaced with the actual application (osso-xterm). This way "master maemo-launcher" can load commonly needed libraries such as glib and gtk at start, fork another instance of maemo-launcher to share those libraries without reloading and start other applications faster.

It's just matter of using swap on microSD (with eMMC swap disabled), and proper swap-related settings.
