[PATCH] D30010: Improve the robustness of mmap

[Rui Ueyama via Phabricator via llvm-commits]

I wonder what this patch is trying to fix on Unix machines. mmap()'ing a file on NFS is not a special thing, and if something goes wrong with NFS, a process will hang whether a file is being used through read(2)/write(2) or mmap. What am I missing?
