This method should acquire an exclusive lock on the resource that is about to be used to read and write the session data.

The lock should only be released in the close method.

Note that this will effectively serialize parallel requests, which affects performance for a single user session.

Not locking the resource would on the other hand allow for race conditions if two or more parallel requests change the session data.
