Hi, well... about the white-space, on my editor the "End Of Line" character is "Unix-style" (only LF)... I don't know if the GitHub Windows Application converts it to CR+LF. I will repost it from the website, or I don't know if I fully understand your exception... 

About unsetting the classes, yes I added and tested a "unset($child)" at the end of the statsQueues function. 

Thanks for checking and explaining!!
