   > Not to mention that we map in 16GB chunks, so may require a little more 
plumbing (but nothing too hard). Is the mapping in chunks still needed? Did you 
@uschindler encounter issues when mapping larger chunks?
   
   Yes, tests on Windows showed havoc with large files.
   
   But this is not a problem form MemorySegmentIndexInputProvider, the mmap 
call is easy to do, the splicing is already there. We just have two 
implementations for the filename -> MemorySegment[]. Easy, no changes needed.
