We're still using 1.5.1 (no comments, please! we're supposed to finally
upgrade this week), and I was wondering if you could explain what the
symptom of this bug is, because we've seen a couple of recent cases
where a heavily threaded app that creates hundreds of single-shot
threads dies with a thread error.

(We're *also* fixing it to use a thread pool, but I'd still like to know
what our chances are of hitting this with the stock 1.5.2)
