Subject: Miles Bader implemented a new mmap based malloc which is much smarter
 than the old "malloc-simple", and actually works, unlike the old "malloc". 
 So kill the old "malloc-simple" and the old "malloc" and replace them with
 Miles' new malloc implementation. Update Config files to match.  Thanks
 Miles!
