[Samba] clients open/close files thousands of times

closed dozens of times a second.  Filling up the with open and closes
everyday, one user with 60,000 pairs of open/close statements in less than
one day.  It seems to happen in different degrees of severity to different
users... Samba 3.0.20c kernel: 2.6.9-22.0.2  Here is an example:
