   mmap's MAP_POPULATE will help to avoid expensive page faults by filling the 
page table with entries (read ahead on a file) MAP_POPULATE has been present on 
Linux since kernel 2.5.46 (20 years ago). 
   
   XXX: Would it be better to scope configure.in to check to see if 
MAP_POPULATE returns EINVAL?
