<pre>In r186025 the readSync method used when traversing the cache files was removed in favor of using parallel async reads to speed up the traverse. The approach used doesn't work for soup, because the IO operations are async, but run their callbacks in the current thread. The network cache now runs up to 5 async reads in the io work queue thread, and waits for them to finish, and those asycn reads never finish for the soup backend because the thread is blocked waiting for them. We need to use a different thread to run those reads.</pre>
