[RESOLVED] Behavior if script terminates before reaching imagedestroy

Does anyone know what happens to a script if an image file is being manipulated (as the result of a imagecreatetruecolor call) and the script terminates before reading the call to imagedestroy that would free the memory? Does termination of the script free the memory automatically or is a memory leak created? If the latter, is there a design pattern to avoid the failure to free memory?

Sorry for such a basic question; I read the PHP man page on the issue and was still confused.

Being that PHP is an interpreted language, resources are not kept past script execution.

Thanks!
