C and C++ (and Rust!) can put objects on the stack, so you have a lot more leeway to write normal idiomatic code without hitting the allocator.

When Java gets value objects, this sort of work will begin to get a lot easier in Java as well, but there will be a lot of catching-up to do.

A very good point. Most of my GC whispering is done in .NET, which also has value types, but I was guessing that escape analysis in Java would solve most of the problems in this regard. Is that not actually the case?
