As mentioned this is primarily the SELinux policy we load. I wished
libselinux would optimize memory usage transparently, but even without
any changes in libselinux we should be able to optimize this a bit.
Yes, using SELinux makes your boot a bit slower and consumes more
resources, there is no news in that, and there's also no news in the
fact that we can optimize this a bit when we are aware of it.
