Can't we force non-threaded compilation when we use %OptimizeFunctionOnNextCall?
Or have it stall execution until function has been installed?

I removed this by accident -- %OptimizeFunctionOnNextCall has correct semantics
even when compiling things parallely.

 
 var a = new Int32Array(1024);
 
 function test_base(base,cond) {
   a[base + 1] = 1;
   a[base + 4] = 2;
   a[base + 3] = 3;
   a[base + 2] = 4;
   a[base + 4] = base + 4;
   if (cond) {
