Thought so. Any reason why we shouldn't?


In contrast to the timeout of the previous paragraph, the idle timeout only
considers the time since the last output was produced by the process::

use Symfony\Component\Process\Process;

$process = new Process('something-with-variable-runtime');
$process->setTimeout(3600);
$process->setIdleTimeout(60);
$process->run();

In the case above, a process is considered timed out, when either the total runtime
exceeds 3600 seconds, or the process does not produce any output for 60 seconds.
