Quick hack to allow Kohana to handle memory_limit and max_execution_time violations.

	 * Augments the core method for two reasons:
	 * 1) Reserve an extra 1M memory to allow handling memory_limit violation.
	 * 2) Reserve more exec time to allow max_execution_time violation.
	 * 
	 * Note: keep variable creation at a minimum.
