They don't.  The issue at hand is that Cygwin uses SeBackupPrivilege and
SeRestorePrivilege if otherwise the object in question would not be
accessible.  The moral of the story is to drop those privileges /
capabilities when you don't need them via cygdrop or just don't use an
administrative account that comes with them in the first place.
