It turns out the problem was only introduced in PAPI in November ( I had 
assumed it dated back further).  So maybe not as dire as it seemed at 
first.  

The fix to PAPI does seem to be trivial, though the whole set of 
bad code was introduced to work around a different problem so I need
to verify the fix doesn't break other things.

Thanks,
