[PATCH] D27295: Remove existing file in a separate thread asynchronously.

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

The reason for unlinking is to get consistent behavior in the error case as well as consistent access permissions.

That said, I can't reproduce the numbers on my laptop. For Ext4 on my laptop, I see around 0.1s for rm to delete a 1GB test file, tmpfs is half of that.
