* 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.
