    Fix Fission (broken by my previous patch)
    
    Turns out somewhere along the refactoring of the multiple-CU support
    for Fission I broke the patch before submitting it (& seems to have
    broken Fission support generally).
    
    Syncing back to the point at which the patch was committed, the
    previous test results on my machine are:
    
     expected passes: 36137
     unexpected failures: 416
    
    with the previous (broken) patch committed:
    
     expected passes: 36131
     unexpected failures: 429
    
    With this one line patch applied on top of the broken commit:
    
     expected passes: 36144
     unexpected failures: 416
    
    (& all other result counts remained the same in all 3 cases)
