Also consider the case where a user syncs after not having updated for a
couple of months, and the tree contains some ebuilds with EAPIs that are
not supported by the currently installed package manager.
In this case, when resolving dependencies and filtering ebuilds based on
whether or not their EAPI is supported, spawning bash once per ebuild is
much more costly than the alternatives.
