The following patch adds a "-clienttimeout" option to the fileserver,
which takes one argument, a number of minutes to be used in aging out
idle client connections.
The 2 hour default is too long in an environment where some hosts
could be creating and abandoning client connections at a high rate
(such as a fileserver that has clients that are running something
nutty like this: http://www.umbc.edu/oit/iss/syscore/wiki/Mod_waklog).
This patch is against the 1.4.2 release.
