I also experienced the problem that the FR slowes down to a point where
it freezes when the memory consumption goes to the limit of the internal
ram. And this happenes quite often when using many programs.
To solve this problem i created a swap file with 64MB on my sd-card
(vfat, but this shouldn't matter) and added it to the fstab like this:
/dev/mmcblk0p3 /media/disk vfat defaults,noatime 0 2
/media/disk/swapfile swap swap defaults 0 0
I know that swap on a sd-card isn't the best thing to to, but i didn't
notice any sd-card performance problems. And since i use this my
freerunner didn't freeze at all anymore because i never get close to the
192MB ram even when starting many programs. :)
