Openly said, based on my experience with my i586, I don't buy this. Usually, the memory requirements introduced other applications are magnitudes above that of yum.
My impression is that our lack of swap really hurts us here; on most systems, it's possible to swap some pages (dirty or clean) at relatively fixed cost and keep going. We _suspect_ (but have not yet proven) that on XOs, under memory pressure, we start thrashing code pages (which can be unmapped since they are clean but which must be de-compressed in order to be remapped) and eventually OOM when we finally receive an allocation that cannot possibly be satisfied.
However I am not sufficiently familiar with OPLC to be able to further comment on this.
If you would like to become sufficiently familiar with XOs to comment further, it can be easily arranged, either through our Developer's Program [1] or through a renewed G1G1 effort scheduled for November [2]. Please consider it -- we could use your help and it's a great way to help OLPC get better at doing things the Fedora way.
