Added tracking for running queries and the ability to reject queries if more then N are submitted at a time.
Fixed a bug in multi caused by the new queue limit. Modified mocha tests to point locally by default.
Removed the callback for multi as it will cause -- leaks.
command callback should not decrement active query count.
Removed sharding, confuses the issue. 1 server is better for replication of the problem.
Removed debugging trace.
Fixed bug where long keys are not hashed. Fixed bug where spaces in key name result in the callback never being called.
Fixed a problem with queueing that caused current active request queue count to be too aggressively torn down when using multikey-gets. This manifested as a memory leak under sustained load when using multikey gets.
Restoring old test settings.
