The session is locked so that the session data is lost or corrupted by 2 
  requests with the same sid arriving almost simultaneously, as might 
happed with page frames, or if the user has multiple browser windows or 
tabs open to the same website.

When the session is locked a cleanup is registered to unlock the session 
when the request is complete.
