	As always, mixing NFS and SMB is immensely useful,
	but sometimes drives you mad [It's what I'm using
	at work, to reduce load on the sysadmin team: we
	no longer have a large number of NT guru-level
	developers, so we can afford the performance hit]

	I'm CCing this to the samba at mailing list,
	as the team is watching out for incompatibilities
	with late-model MS products, including win2k and 

[paraphrase] The user in question often accesses the same
file from any one of a pool of machines, and it looks like
the hand-off from machine to machine isn't being dome cleanly.

	That makes me nervous... anyone know if this is likely
	to be an interaction with NFS???

	This is a good idea, especially if it's this user's
	private directory, so that other users still get oplocks.

	If it's [homes] instead, You might try adding 
		include = /opt/samba/lib/extra.%m
	to the homes share and and creating a extra.<the name of 
	the user> file  which contains "oplocks = no".

	That way only that particular user gets his oplocks turned off.

	pkill will whack his normal processes, but for samba you
	may need to write a script that looks at smbstatus output
	to see which pid to kill.
