I think I recall that Ruby 1.8 was supposed to get a new garbage collector. It appears not to be the case. However, I wonder whether there's a patch that I could apply to Ruby (1.6.8 or 1.8.0) that would improve the "realtimeness" of Ruby in any way. Specifically, I mean anything that would make the worst-case duration of a GC interruption smaller. ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju
