MaxConcurrentExecutions

If set this throttles the number of concurrent executions that can occur of the underlying command handler when the cache misses. This can be useful when the underlying request is expensive and hitting it with multiple requests simultaneously could cause failures. This is mostly intended for scenarios with high levels of requests / transactions. Note that the implementation for this uses a double lock approach with a semaphore and so anything that finds itself blocked due to the throttle should find the result in the cache. Should further be noted that this lock is obviously within the process and not shared across servers.
