(A further update - I decided to engage brain this time)

	Well its paniced twice in nfsrv_rename(), and now doubt will
	do so again (MTBF < 3 hours).

	Apologies for all the bits of mail - I'd have collected it all
	together first but the machine is the main server for mono.org,
	and the downtime is hurtin' :)

	Thanks again for any help

		David
