Cool, but very often my keystrokes aren't showing up, making this pretty unusable.

Also, for the use case of local dev environment for Web IDEs, this doesn't look fast enough.

    node --version

runs fast after the first time, but executing any JavaScript is very, very slow:

    user@:~$ time node -e "console.log('Hello')"
    Hello
    
    real    0m7.693s
    user    0m0.012s
    sys     0m0.000s
