Are you sure this should be MFC'd?  While I agree with the change in 
principle, it will cause systems currently using malloc-backed md devices to 
mysteriously switch to swap-backed.  How will this behave on systems that 
don't have swap, such as pure diskless systems not using NFS-backed swap? 
This isn't a strong objection per se, but it could be that rc.d scripts need 
tweaking for diskless environments if they currently do use malloc-back md 
devices based on that being the default.
