The current doc states max ram for a test VM would be 7.5G, the currently used container image has even less. This skip should be revisited, as the available memory amount shifts. The way of checking /proc/meminfo doesn't work reliably on containers at least, thus skipping explicitly on Travis-CI makes sense.
