Node.js weirdness with child processes and signals

example.js

var blah = setTimeout(function () {
  console.log('example dying');
}, 30000);

var blah2 = setTimeout(function () {
  console.log('example debugging');
  process.stdout.write('example debugging');
//  debugger;
}, 5000);

process.on('SIGINT', function() {
  console.log('example got sigint');
  process.stdout.write('example got sigint');
});

process.on('SIGTERM', function() {
  console.log('example got sigterm');
  process.stdout.write('example got sigterm');
});

process.on('exit', function() {
  console.log('example exiting');
  process.stdout.write('example exiting');
});

process.stdout.write('example writing to stdout');
