No cigar.  The attached changeset fixes a problem where the preIncrement
operator was failing to attach the global struct prefix to its operand.  
After applying the changes, adding


and regenerating the VM, I get a working, non-inlined VM:

 '75294117 bytecodes/sec; 2931774 sends/sec'  (regular)
 '10914051 bytecodes/sec;  594140 sends/sec'  (non-inlined)
