Since bootstrap/node.js performs the setup synchronously, the process exception handlers do not have to setup so early in the bootstrap process - any fatal errors thrown before user code execution should simply crash the process, and we do not care about any clean up at that point. We don't care about emitting any events if the process crash upon bootstrap either.

There was a problem hiding this comment.
The higher-order bit is that everything below this point (plus setupTraceCategoryState() and process.argv[0] setup above) is environment-dependent and should be moved out of node.js - then it would be possible to snapshot Node.js after the execution of this script, which would be dedicated to setting up the process object and global proxy synchronously in an environment-independent manner.
