Ahh, that would explain the bandwidth alert from my VPS this morning. Thanks; good to know Apache HTTPD mod_cache stands up to a hug-of-death.
This seems to happen on Hacker News, Reddit, or Lobste.rs every year or so, and the discussion always features the same sort of debate about the use of the term "IDE". I'm not sure I'd title it this way if I wrote it again. I don't really mind, though. I'm glad people still seem to find it interesting or useful. Some of it needs a bit of updating, really.
