Based on ideas in js-async-init, this optimises the stack trace slicing to use indexOf rather than splitting and joining. Also the check for captureStackTrace and stackTraceLimit is now done statically.
I've also mocked out the console.error and process.stderr.write so that way we don't get weird looking messages when running tests.
