This is important enough of a usage note that I'm going to probably mention it in my software's documentation. I personally largely ignore this issue and thing I'm probably safe doing so with my usual testing workflow, but it is an easy thing to burn yourself on if you sit and watch your dashboard all day.
Crikey, how did that fall off my list? I have a half-written analysis sitting in my home directory. It will probably take me a few days to finish the other half: I have a couple things ahead of it in the queue and this next application isn't going to write itself.
