Why are you using locking with your sessions? Are you doing something that truly requires it? You already have atomic updates if you use database-backed session storage. Consider moving this data out of your session and passing it in URLs instead. Consider separating out the slow part of handling this request into a forked process, so that the session is not locked during the whole calculation. In other words, look for a way to avoid the root of the problem: doing a slow operation and keeping the session locked the whole time. - Perrin
