I'm not sure that this is a valid analogy.  The "CreateProcessAsUser"
example is really an indication of a "bug" in cygwin.  It's an
indication of a non-fully-functional setuid (or something).

The goal would be to make the CreateProcessAsUser requirement go away
in a future version of cygwin.

Maybe I'm just optimistically holding out for some clever solution in
stat() that will speed things up so much that stat_lite is not required.
