So, rather than reinvent the wheel, I just ported the Clojure collections over, added generics and made them more Java-ery [1] In the Clojure world, (and indeed in Haskell and other pure-fp languages) there is a lot more garbage collection. Rich Hickey makes a great case for this trade off here [2]. On the JVM now very little of it is stop-the-world GC, it mostly does incremental. It's been a while since I profiled a Java app in anger, but even back on JDK5 this was the case, and I know they changed it significantly in JDK7 to the G1 collector.. anyone have a clue about that?
