Does anybody know why access checks file accessibility using the real [ug]id
in place of the effective [ug]id? It seems to me that access should agree
with open(2) as far as whether a program has write or read access to a file.
Inside a set-uid program that assumption obviously doesn't work while
uid != euid.

Should access have been implemented the other way or should another
version of access (eaccess?) exist or am I brain damaged?

Is there a better way of implementing eaccess than using open/close, assuming
I don't have the file already opened?
