Calling process.send('complete') more than once

[lfreneda]

Is not possible to call process.send('complete') more than once from workers.
Is there an alternative to comunicate with the compute cluster?

For example:

simple.js

#!/usr/bin/env node

const computecluster = require('../lib/compute-cluster');

// allocate a compute cluster
var cc = new computecluster({
  module: './simple_worker.js'
});

var toRun = 10;

// then you can perform work in parallel
for (var i = 0; i < toRun; i++) {
  cc.enqueue({}, function(err, r) {
    if (err) console.log("an error occured:", err);
    else console.log("it's nice:", r);
    if (--toRun === 0) cc.exit();
  });
};

simple_worker.js

process.on('message', function(m) {
  process.send('complete');
  process.send('complete');
});

the output will be: it's nice: complete 10 times, not 20.
