It would be nice to fix a class init optimization problem. The compiler
should recognize that calls to constructors and calls to static methods
always initialize the called class, so we can force our
class-init-tracking local flag to `true' whenever we do these. 
public class A
{
 // This method should never call _Jv_InitClass on B.
 public int foo ()
 {
 B b = new B();
 return B.bar;
 }
 // Neither should this.
 public int foo2 ()
 {
 B.plus6(5);
 return B.bar;
 }
}
public class B
{
 public static int plus6(int x) { return x + 6; }
 public static int bar = 555;
}
I don't think the fix is very difficult (I hope!).
Is it too late to put this kind of change in for 3.4?
