I don't know, none of those things really sound like justification for
a separate TLP, keeping something like this nearby to Hadoop MapReduce
seems like it would help give it a better chance of long term survival
 to me. Wouldn't simply moving mrunit out from
hadoop/mapreduce/trunk/src to somewhere else so it can do its own
releases and deploy its artifacts achieve all those objectives?
