As for ProcessTimedOutException, it would be great to have an exception when a signal has been sent to the sub-process.

Basically, on this line:

symfony/src/Symfony/Component/Process/Process.php

Lines 389 to 391 in 1df45e4

	if ($this->processInformation['signaled'] && $this->processInformation['termsig'] !== $this->latestSignal) {
	throw new RuntimeException(sprintf('The process has been signaled with signal "%s".', $this->processInformation['termsig']));
	}

This would allow to catch signaled sub-process on a higher code level and retrieve the concerned process when running many, thanks to the process property of the exception.
