Yes.

Hudson keeps the workspaces and only updates.
I commented out the clean-all from the test jobs for the time being.

I'm going to setup a compilation job for m3cc on each platform,
and let that trigger the cm3 builds. Of course m3cc building is
triggered by CVS, we we must include m3cc CVS chanes from triggering the
other jobs.
