WASession >> #unregister does signal an error

[dalehenrich]

Ran into this when I clicked on New Session button in counter while testing not tranlogged in Seaside3.2 ....

Here's the stack (frame 13 is the bad boy) and the arg to #remove: is a WASession instance:

Not exactly clear what needs to happen here, since compatibility needs to be maintained with alternate cache implementations ... or removeKey: needs to be used ...

[dalehenrich]

@marschall could you share your thoughts about this particular problem .... it appears that the only solution involves using keyAtValue: which can be pretty expensive ... alternately one would have to implement a bi-directional bulk reaping cache ... or ???

I'm going to go with keyAtValue: for the time being, because I need to find out if there are any other changes (like WASession continuations references and a possible change to WASnapshot) that might be needed for Seaside3.2 to use not tranlogged objects ...

[marschall]

The session cache in 3.2 is key → value only which makes the implementation much simper (and use a bit less memory). Which means we can't do #remove: which would require a slow #keyAtValue:

But there is a simple fix. A session now knows it's id, I just need to override #unregister in WASession.
