: Presumably the only really correct solution here is to:
: 
: 1) Set effective process rights to that of the user in question using
:    setusercontext()
: 2) Open the file using open()
: 3) fstat() the file to determine that it is regular and sane
: 4) Proceed with operations

I'm not sure I understand the need for #3.  If the effective process
rights are what you want, then the kernel will enforce protections at
#2.  What's is regular and sane?
