Before parallel-install there was just one big lock, so only one package slot could enter the merge/unmerge state at a given time. With parallel install, there are a few finer-grained locks that come into play. These are the really important ones: * When merging/unmerging files, an exclusive lock must be held on vardbapi._fs_lock. * When executing an unsandboxed ebuild phase, an exclusive lock must be held on the FEATURES=ebuild-locks lock. -- Thanks, Zac
