    nmalloc - Improve incremental reallocs()
    
    * Fix realloc() issue that caused unnecessary unmap/remap operations
      due to the page coloring optimization.
    
    * In addition, scale large reallocations by allowing more wiggle room
      as the allocation becomes larger so overhead isn't quite as geometrically
      bad for programs which do incremental realloc()s to huge sizes.
    
    Initial-patch-by: vadaszi Bug #2832
