I have a job configured on my Windows master Hudson to run on my Suse slave box
at 8:30pm. The job always start successfully. However, shortly after 10pm each
night, while my slave build is still going, the Windows master does a workspace
cleanup and deletes the "builds" directory on my slave which of course fails the
build. I can see this by seeing the timestamp on the workspace-cleanup.log file
on the master system in HUDSON_HOME. The text of the file says:

"Scanning <my-suse-slave-machine>
Deleting /hudson/builds/workspace/builds"

... where "/hudson/builds" is the defined FS Root of my slave configuration.

I have searched for a setting to prevent this cleanup but have not found one
yet. It seems that hudson is not recognizing that a slave build is in process.

Note that I have not updated slave.jar since earlier 1.2 releases as I assumed
it has not changed. Thank you.
