6to5-node breaks Node uncaughtException handler

[atombender]

Test case:

process.on('uncaughtException', function(error) {
  console.log("uncaught");
});                       
throw new Error("Argh");

With Node:

# node test.js                            
uncaught

With 6to5-node:

# 6to5-node test.js
/tmp/test.js:6
throw new Error("Argh");
      ^
Error: Argh
[...]

6to5 doesn't intercept uncaughtException anywhere. It's likely a problem with source-map-support. Can you report it upstream?
