      Description

      The Fetcher class only has a blocking way of waiting for outstanding requests to complete. This is a problem in cases where we need to use the Fetcher from inside a thread pool. We should either create an alternative Fetcher class (e.g. AsyncFetcher) that provides a non-blocking version of the same functionality, or refactor the AsyncFetcher to allow it to provide both blocking and non-blocking APIs, and probably implement the blocking ones in terms of the non-blocking ones.
