It's not. Matt likely wants my experienced opinion and definitely wants me to weigh in where a programming change is concerned since I'm the one who'll get saddled with it.
Matt, programmatically, if you want to change the limit to another length of time, that'd take me seconds to do.
If we want to make the limit only apply to threads in certain categories, that's do-able but would take longer. I'm not sure how much longer as I don't remember how that routine works.
