On Windows, calling Unix.clear_non_block and Unix.set_non_block is only supported on socket file descriptors. The function is_blocking already deals with the corner cases, but the current implementations of dup and dup2 don't make use of it. Thus, when then dup or dup2 wrappers are called with file socket descriptors, ENOTSOCK errors are raised. The fix is to reuse is_blocking in the wrappers.
