Aha, for the "promise" library I need to chain "catch()", eg:

var P = require('promise');

P.all([1,2,3]).then(function(results){
    console.log('P.all success, results', results);
    var a = invalid.property; // oops
    console.log('after the invalid property')
}, function(err) {
    console.log('P.all error', err);
}).catch(function(err){
    console.log('some error occurred', err);
});

#output:
node exception.js
P.all success, results [ 1, 2, 3 ]
some error occurred [ReferenceError: invalid is not defined]
