Before this patch, a log reader is able to block all log writes indefinitely (and other operations) by simply opening the log stream and not consuming all the messages. The reason for this is we protect the read stream from corruption by ensuring there are no new writes while the log stream is consumed (and caught up with the live entries). We can get around this issue because log files are append only, so we can limit reads to only the section of the file that was written to when the log stream was first requested. Now logs are only blocked until all files are opened, rather than streamed to the client.
