In particular, I note that all files in the bytestring-mmap repo have:

     Stability :  provisional
     Portability: non-portable -- posix only

are either of these a cause for concern?  Is our existing NIH mmap
implementation used on Windows?  (I assume Windows' POSIX support isn't
adequate for "posix only".)
