A port I did of Seaside to VW 5i.4 had one problem which produced 
exactly the symptoms above.  So you could quickly check this out.

My problem was with the weak collection I had selected for use in 
SeasidePlatformSupport class>>weakDictionaryOfSize:.  If this has 
incorrect semantics then WAStateRegistry will do some strange things.

A suitable test is to replace the weak dictionary with an 
IdentityDictionary.  If your transactions start working....
