Most Seaside objects are not thread safe as they are meant to be used
only within the request-response thread. WASession is one of them
that's why it's normally behind a WAMutualExclusionFilter. In theory
any forked access to a session should go through that mutex. In
addition forked access to a session is not recorded in the session
cache so it may expire at any time. If you need session data in a
forked process the recommendation would be to factor that data out
into an immutable object and store with object in the session and pass
this object to the forked process.
