Didn't get the original mail (yet), so replying to this one instead.
I don't know if the issue is already fixed in the kernel used on the
XO-1, but Linux has a very old bug that causes the system to slow down
to a crawl if no swap is enabled and memory is getting tight.
I'm afraid I don't have any references, but still encountered it some
weeks ago when installing Linux on my phone. Once I enabled swap
everything was fine.
PS: FUP2 set to sugar-devel
