I'll watch out for this.  In the end, I was thinking I'd just turn on  
the optimizer and ensure that we get the nice codegen out of the  
compiler.  This would help ensure we have nice tight code for thunks.   
In the end, there is almost no wiggle room for thunks, which should  
ease the testcase maintenance burden.
