Ruby's GC is a steaming pile of shit — but that's not news to anybody. If you're running ruby in production, tracking GC behaviour is essential so that you can minimize its effects on perceived performance (hence oob_gc, etc). Fortunately, Ruby 1.9.3 ships with GC::Profiler, which provides detailed instrumentation on GC runs.
