* We need to collect all stdout and stderr and store it, so the caching mechanism

* Writing stdout and stderr into different streams is too risky when using TTY.

* So we are simply monkey-patching the Javascript object. In this case the actual output will always be correct.

* And the cached output should be correct unless the CLI bypasses process.stdout or console.log and uses some

* C-binary to write to stdout.
