[Haskell-cafe] Cheap ByteString mmap

[Don Stewart]

A little mmap binding for ByteStrings.

    http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bytestring-mmap-0.1.1

Should be useful for managing file resources under pressure (cheaper
than a readFile, and with different constraints).

Posix only. the Win32 mmap for bytestrings is in the win32 package.
