[Samba] file corruption with write cache

[Holger Krull]

Hello,
FYI, i noticed that using
 write cache size = 131072
on a share, leads to corrupted files from some applications. Only one client is accessing the file.
In particular with coreldraw this can be reproduced.

Setup: 
Server: samba 3.0.4-SUSE 
Client: Windows XP Pro

[raid1]
        comment = 1
        path = /raid1
        read only = No
        create mask = 0777
        directory mask = 0775
        write cache size = 131072
        map system = Yes
        map hidden = Yes
        delete readonly = Yes
