I think Epsilon supporting System.gc() / Runtime.getRuntime().gc() would be very useful. And if the behavior isn't wanted, well there is always -XX:+DisableExplicitGC. And that will do what? System.gc() requests are ignored by Epsilon, because there is nothing to do. I believe he wanted to say that it'd be useful if it did something (i.e. collect garbage). I presume the idea is to never do GC, except when explicitely requested. Yes, I was saying that in contrast to doing no GC, I would find it useful to have a GC system that only collects on demand.

OK, but that is not one of the goals of Epsilon. It's a reasonable idea, but it's another project.
