I too had this but it only happend when I did a '/bin/ls' in /usr/doc/grub.. It
would start taking up all my memory and swap until it would kill 'ls'.. I could
reproduce it more than once until it killed X. After that it hasn't
happend again.

I have 187MB of ram and 191MB of swap.

I got the following output by running vmstat 1 and then doing the /bin/ls in
/usr/doc/grub.
