Subject: [PATCH] Get rid of special mmap decision on Windows.

I spent some quality time on my Windows 10 laptop and it appears to
suffer from a similar trade-off as on Linux: mmaps are bad for large
directory traversals but good for single large files.

Darwin continues to reject memory maps in all cases (unless explicitly
requested), but more testing should be done there.
