At least back when I was looking at this problem (5+ years ago), memory mapping was the key -- I was not able to delete the process if the file was mapped -- regardless of the open flags. That said, [this comment](https://github.com/llvm/llvm-project/blob/4d218caa7716743061e8d34d61b2181c94b16440/llvm/lib/Support/Windows/Path.inc#L921C1-L925C20) seems to indicate this might be possible (though it may refer to FILE_FLAG_DELETE_ON_CLOSE rather then an separate delete operation), so :shrug:

Either way, I think this change is fine, as we don't really want to enforce that the file *can't* be deleted if the source cache setting is "true".
