	And of course to any process with appropriate capabilities set, on
Unices that support capabilities (e.g. Linux)

	Indeed.  This also means that a semantically-correct mapping between
Unix and NT permissions is not possible.  When passing permissions info to
the NT side, you have to resign yourself to just translating the permissions
syntactically as close as you can, and let the user at the other end of the
UI worry about the semantics.
