A couple questions: 1. Is the memory usage fairly constant, or is it growing? There was a memory leak in Rails 0.14.2 (I think) that caused Typo to grow without bound; that leak has been fixed, but there could be other leaks. 2. How much memory is Typo using. I keep hearing numbers like "lots", but I've only seen one set of numbers so far. I'll try to look into this soon, but I need to fix a few bugs first, and my schedule has been fairly unpredictable lately.
