When it goes out of scope it gets freed. But I do vaguely remember
something in the lines of you are not guaranteed when it gets freed.
But with my testing it gets freed pretty quickly.
I use interfaces for logging (entering & exiting procedures) and for
reseting the mouse cursor when a method exits.
