Part of the problem is that Java wants to put (almost) everything in the
heap.  The GC would be faster if more data could be allocated in the
stack, or in registers.  Many GC'ed languages share this problem.

The C# language is nearly identical to Java, but one important
difference is that you can have stack-allocated structs.
