	You may find you have some problems with userland programs that
	depend on the broken semantics of the old ("New" mach), vfork().

	A simpler option might be to update to -current. That allows you
	to switch between the Mach VM and UVM by just defining 'UVM', plus
	bringing forward the old ("New" mach) vfork() semantics should not
	break anything else.
