    Oleg,
    	This patch probably needs review for any races we may have
    missed to account for.  Also we have considered only workqueue.c present
    in 2.6.20-rc6-mm3, which means some recent patches in mm tree which are
    yet to be published arent accounted for.
    
    Also I expect almost all worker threads to be frozen "for hotplug". The
    only exception I have found so far is kthread workqueue, which needs to
    remain unfrozen "for cpu hotplug" because kthread_create (in
    CPU_UP_PREPARE and stop_machine) relies on its services (while everyone else 
    is frozen).
