This patch traces all public async methods and wraps them in a helper method that tags the sync stack trace. Later on, if the method call throws an exception, we add a captured stack trace to the original stack trace with the "--ASYNC--" heading. An example of a stack trace: ``` Error: net::ERR_ABORTED at http://localhost:8907/empty.html at navigate (/Users/lushnikov/prog/puppeteer/lib/Page.js:622:37) at process._tickCallback (internal/process/next_tick.js:68:7) -- ASYNC -- at Page.<anonymous> (/Users/lushnikov/prog/puppeteer/lib/helper.js:147:27) at fit (/Users/lushnikov/prog/puppeteer/test/page.spec.js:546:18) at process._tickCallback (internal/process/next_tick.js:68:7) ```
