    I have no idea what the frig you guys are doing in vm_map.c.  I would
    recommend that all the changes be backed out.  Then I would recommend
    that the following be done:

	* change the lockmgr vm_map lock to be exclusive-only
	* test & commit
	* change the lockmgr vm_map lock to an exclusive SX lock 
	* test & commit
	* Then work on re-optimizing the vm_map locks

    You guys are trying to bite off too much all at once.
