Timing condition causes "An unknown error occurred" message instead of useful one

[MattJaniszewski]

Using the following code (sans namespaces and autoloader config):

$dispatcher = new EventDispatcher();
$manager = new ProcessManager($dispatcher);
$manager->setDebug(true);

$callback = function($item) {
    if ($item == 1) {
        throw new \Exception('This message should be shown');
    } else {
        sleep(1);
    }
};

$manager->process([1, 2], $callback, new ChunkStrategy(2));
$manager->wait();

I get the following output (sans stack-trace):

PHP Fatal error:  Uncaught exception 'Spork\Exception\ForkException' with message 'An unknown error occurred in "<anonymous> batch" fork (13677)' in /home/matthew.janiszewski/source/spork/src/Spork/Fork.php:91

If I comment out sleep(1); in the example above, I get the predictable message:

PHP Fatal error:  Uncaught exception 'Spork\Exception\ForkException' with message 'Exception (0) thrown in "<anonymous> batch #0" fork (14551): "This message should be shown" (/home/matthew.janiszewski/source/spork/error_test.php:31) via "<anonymous> batch" fork (14550)' in /home/matthew.janiszewski/source/spork/src/Spork/Fork.php:91

Ideally, in both cases "This message should be shown" should be displayed, rather than only in the latter case.

Hi. Do you fixed this issue?

Sometimes, I receive the following error:

  [Spork\Exception\ForkException]                              
  An unknown error occurred in "<anonymous> batch" fork (952)

Thank you!

Hi.
I fixed this error. Fatal error was found in my methods.. Spork does not show this error.
Thanks.
