Drop an unnecessary use of writev. It looks like the code this patch deletes is based on a misunderstanding of what guarantees writev provides. In particular, writev with 1 iovec is not "more atomic" than a write. Testing on OS X shows that both write and writev from multiple processes can be intermixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@255837 91177308-0d34-0410-b5e6-96231b3b80d8
