chromium 的render process创建堆栈

1、通过BrowserThread::PostTask的调用堆栈：

content.dll!content::ChildProcessLauncher::ChildProcessLauncher(const FilePath & exposed_dir, CommandLine * cmd_line, int child_process_id, content::ChildProcessLauncher::Client * client)  行 401	C++
 	content.dll!content::RenderProcessHostImpl::Init()  行 471 + 0xb0 字节	C++

这个案列对理解chromium的多线程异步和进程创建有一定的帮助。
