Description:
------------
I am running a gearman client script that runs a series of tasks in the foreground, but also has a pcntl_signal(SIGINT, ...) signal handler.  While the runTasks() call is running, I cannot press Control-C to exit the script.

For example, I am running the client example at http://php.net/manual/en/gearman.examples-reverse-task.php, except I added the following as the first line:

pcntl_signal(SIGINT, function() { echo 'sigint'; });

When I run this script, assuming no workers are available, I cannot press Control-C to exit the script.  I have to run kill -9 to end it.

Is there a way that I can use a SIGINT signal handler and still use runTasks() to run a series of parallel tasks over gearman in the foreground?

Alternatively, could runTasks() be changed to optionally throw an exception on a SIGINT rather than exiting the script?
