Hmmn, Multics and perhaps Knuthput used to have an "initiate" 
call which you used before an open, but if I understand it correctly
the Unix folks rejected it as overly racey, and defined (f)open
and fstat, used in that oder.

Are there cases where we actually need the full accessibility
information but aren't going to open the file?  That does
seem faintly implausible...
