Well, the my testing showing that compcache is more robust with that
with no swap at all under low memory situations. This would have been
enough for Ubuntu if not for the feature freeze. In any case,
benchmarks would be good.

Are the scripts used to do that benchmark available? (I know
XAutomation is already available in Debian)
