Description Zac Medico gentoo-dev

Currently, FEATURES=parallel-install does not check for file collisions between packages that are installed at about the same time, since it would have to re-run the collision-protect routine that runs prior to pkg_preinst.

We can add a FEATURES=parallel-install-collision-protect option that will cause the collision-protect routine to re-run prior to merge of the package files, ensuring that not file collisions can go undetected.
