>> I am intrigued about the ORIGINAL needs of such a need. Because as Pharo and GemStone and too it makes me wonder if the lock would be needed on GemStone.
> I've read some of the newer Seaside code and while I can easily tell that there is still session state being copied and restored (see senders and implementers of snapShotCopy and restoreFromSnapShot:), it is not easy to tell how it is being protected from logical or physical corruption ... WACache has a mutex protecting the cache updates, but I still don't see how the component snapshots are being protected from concurrent updates ...
That should be the WAMutualExclusionFilter, no?
This one is never installed in the Gemstone code.
