+ We have run the PigMix suite on a Hadoop cluster to compare this enhancement 
to the code in the trunk. Here are the results (average over 3 runs):
+ 
+ ||Test Case||Trunk||MultiQuery ||
+ ||L1 ||4min07sec||4min10sec||
+ ||L2||1min46sec||1min54sec||
+ ||L3||5min12sec||4min40sec||
+ ||L4||2min39sec||2min36sec||
+ ||L5||2min15sec||2min14sec||
+ ||L6||2min27sec||2min28sec||
+ ||L7||2min14sec||2min06sec||
+ ||L8||2min07sec||2min01sec||
+ ||L9||8min58sec||8min42sec||
+ ||L10||9min10sec||9min15sec||
+ ||L11||3min23sec||3min28sec||
+ ||L12||10min14sec||2min47sec||
+  
+ L12 is the only multi-query script in the suite and we see 70% performance 
improvement. For the non-multi-query scripts, the performance is unchanged.
