In fact, Robert Mustacchi added process.abort() in Node 0.7. It just calls the underlying abort(3C), which will usually cause your program to dump core. The trick is calling it from somewhere where you still have enough context to debug what's going on -- ideally, where an exception is thrown. Geoff: That’s a good thought.

It would be great if there was something like process.abort we could call. I'm sure eventually we'll see this sort of debugging functionality outside of mdb/illumos land. Awesome.

If people are using this, I'd recommend keeping either the folded-stack file or the original stack file (which is larger but more detailed), so that they can be reprocessed as we develop the flame graph software further (via either the node.js or Perl versions). Nice!
