	[ML]  But only if the quotas have been turned on.

	BTW, has chown been "fixed" to the ludicrous SysV semantics that
the root and owner can chown a file?  If so, the latter has to be
disabled in presence of quotas on the volume--otherwise:

	touch big_file
	chmod 777 big_file
	chown root:wheel big_file
	cat /dev/zero >>big_file

	This joke used to work on HPUX 10.something which kept the
owner-may-chown semantics even in presence of quotas.  It was not funny.
(I don't know whether HP has fixed that).
