Eh? There's only one client, and it's idle. Presumably it's holding
an oplock.
When I want to edit a file directly on the server, opening for write
stalls for a long time. Presumably the lease causes Samba to send a
break_lease to the _one_ client. Being an idle client that's not
holding the file open, it should respond immediately to break_lease,
and then Samba should let me open the file locally.
That's how leases are supposed to work, but something in that whole
arrangement isn't working properly. Samba is 3.0.6-r3, kernel is
2.6.8 (both gentoo versions).
