Mapreduce limits / scalability

I have recently started using Riak and had a question about mapreduce queries.... is there a limit on the number of queries that could be run concurrently (per node / cluster etc)?

Also, does Riak optimize concurrent requests for the same mapreduce query / queries by returning results from a query in progress (or is there some way to cache query results for some short period of time and return the cached results if the query is re-issued within a timeout period)?
