cli 'restart' with .in().listen().in().listen() prevents workers from respawning

similar to #149, but i realize I'm still experiencing the issue that is most critical

var path = require('path');
var cluster = require('cluster');
cluster(require('http').createServer())
  .use(cluster.pidfiles())
    .use(cluster.cli())
    .in('development').listen(3000)
    .in('staging').listen(3020)

~/code/cluster_test node server status

master 32251 alive worker 0 32252 alive worker 1 32253 alive worker 2 32254 alive worker 3 32255 alive worker 4 32256 alive worker 5 32257 alive worker 6 32258 alive worker 7 32259 alive

~/code/cluster_test node server restart

~/code/cluster_test node server status

master 32266 alive worker 0 32252 dead worker 1 32253 dead worker 2 32254 dead worker 3 32255 dead worker 4 32256 dead worker 5 32257 dead worker 6 32258 dead worker 7 32259 dead

If I comment out the second .in() it works as expected.

var path = require('path');
var cluster = require('cluster');
cluster(require('http').createServer())
  .use(cluster.pidfiles())
    .use(cluster.cli())
    .in('development').listen(3000)
    //.in('staging').listen(3020)

~/code/cluster_test node server status

master 32297 alive worker 0 32298 alive worker 1 32299 alive worker 2 32300 alive worker 3 32301 alive worker 4 32302 alive worker 5 32303 alive worker 6 32304 alive worker 7 32305 alive

I am unable to discover why this is. I know that process.kill() doesn't throw an error.

I added some code to tap into all the events master emits:

var path = require('path');
var cluster = require(path.join(__dirname+'/../cluster'));
var master = cluster(require('http').createServer());
['start', 'worker', 'listening', 'closing', 'close', 'worker killed', 'worker exception', 'worker removed', 'kill', 'restarting', 'restart'].forEach(function(event) {
    master.on(event, function(){ console.log(event); });
});
master
  .use(cluster.pidfiles())
    .use(cluster.cli())
    .in('development').listen(3000)
    .in('staging').listen(3020)

here is working start/restart sequence: start worker worker worker worker worker worker worker worker listening $ node server restart restarting start worker worker worker worker worker worker worker worker listening closing kill worker killed worker killed worker killed worker killed worker killed worker killed worker killed worker killed close restart

here is failing start/restart sequence:

start worker worker worker worker worker worker worker worker listening $ node server restart restarting start listening closing kill worker killed worker killed worker killed worker killed worker killed worker killed worker killed worker killed close restart
