Taking it a step further the function could take an arugment that says why the
check is being done (bind to priveleged port, read a file I don't own) and
would setup the necessary privelege.  This would allow systems that have fine
grained privelege to use it, a subsequent call would be made to drop the
privelege after it was no longer needed.
