I thought about it. The problem is that few lines above there is a comment (in
getFD()):
// Handle "-" as stdout. Note that when we do this, we consider ourself
// the owner of stdout. This means that we can do things like close the
// file descriptor when we're done and set the "binary" flag globally.
and all such stream are created with ShouldClose flag explicitly set to `true`.
Should we remove all this stuff?
