Addendum: seven years later, Windows finally supports pseudoconsoles. If you are running on Windows 10 v1809 or later, this new API should solve your problem.

The Windows Console was extended to have a PTY interface called ConPTY in 2018.

Optimization in this case is nothing crazy, just something I neglected while designing the framework.

The new call API is much more consistent and takes away another thing we kept explaining to new users - an indicator for a flawed API.
