The usual, almost expected high quality of comments. I only had to
change some minor things like that WALRUCache is used to store the
last n continuations of a session, WADocumentHandler can handle
anything that understands #asMIMEDocumentType: and more explitly
explain the behavior of useSessionCookie. I thought I once added a
very helpful comment to WAProcessMonitor but I must have dreamed that.

Thanks for all the hard work.

Cheers
