process.send() should be synchronous, it should block until the message
has been sent in full, but it wasn't after the second-to-last libuv
upgrade because of commit libuv/libuv@393c1c5 ("unix: set non-block
mode in uv_{pipe,tcp,udp}_open"), which made its way into io.js in
commit 07bd05b ("deps: update libuv to 1.2.1").

Commit libuv/libuv@b36d4ff ("unix: implement uv_stream_set_blocking()")
as landed in io.js in commit 9681fca ("deps: update libuv to 1.4.0")
makes it possible to restore the synchronous behavior again and that's
precisely what this commit does.

The same line of reasoning applies to `net.Socket({ fd: 1 })`: creating
a socket object from a stdio file descriptor, like the `process.stdout`
getter does, should put the file descriptor in blocking mode for
compatibility reasons.

Float patch to fix pipe on Windows. Original commit message:

  win: fix pipe blocking writes

  In the code path for pipe blocking writes, WriteFile is already
  posting a completion packet to the I/O completion port.
  POST_COMPLETION_FOR_REQ was causing the same request to get
  returned twice by GetCompletionStatusEx.
  Also on the same code path, we were waiting on the wrong event.

  We need to update queued_bytes and write_queue_size when a
  blocking write request completes asynchronously.
