-This is the [[libnetfs: `io_map`|open_issues/libnetfs_io_map]] issue.

-There is a `NO_MMAP` conditional in Git's source code, but it is a compile-time
-conditional.  The fallback code in `compat/mmap.c:git_mmap` only supports
-`MAP_PRIVATE`, and simply `pread`s in the requested portion of a file.  This
-could be made a runtime fallback, too.
