It seems to me a mistake to allow users to chown files to somebody
else -- IF you run an open shop and are subject to possible malicious
users. Two reasons:
	1) I can chown core files to somebody else and he will
	   have to pay for them (where disk usage is billed for)
	2) I can make a setuid program that does an `rm *',
           chown it to joe, and run it in joe's directory.
	   Bye bye joe's files.
If you run a small, closed shop then it's a nice feature.
Like to see it a system administrator's choice (i.e., a #ifdef somewhere).
