Nokia770-26:~#   

I switched off my swap partition (swapoff /dev/mmcblk0p2 as root) and open 
some apps: as soon as the ram is filled up with apps I get the expected 
warning with chckboxed asking me to kill an app due to lak od memory. That is 
okay. 

Here is the dmesg output. At the end you can see that I switch on swap again.

As soon as I have the swap back on I get no warning check box, but more than 
two apps or so won't start. No warning - no nothing. 

Maybe this is all due to an swap space problem / corupption and it is a 
coincident that I noticed this problem _after_ I installed Canola. 
If this is how it happed than I am absolutly sorry for blaming Canola ;-)
