I think that because I've frequently noticed that when I post to even the most active of threads, it dies.
This is the first time I've killed a forum.
Turns out this is a "feature" of the VS Test thingy. I found a reference to it in a post about performance testing saying something to the effect that you can't rely on [ClassInitialize] and [ClassCleanup] when using them in unit testing.
I'll post about my next problem in hopes of reviving the forum to a state of at least semi-zombie if not full and unfulfilled life.
