Exactly the reason why even IIS has the ability to recycle application pools - kill, spawn a new one. Any garbage that accumulated in the previous instance dies with it.

Nowadays, I'm setting such things to run as scheduled tasks and be recycled every hour. Even though the screen savior that I wrote runs over the whole weekend and still doesn't grow above 38 megs. Justin Case is my friend (and so is that Japanese guy, Itsokei).
