The VW garbage collector *does* remove the unreferenced instances,
it just does not tell you when.

You can get rid of expired sessions using this :

Seaside.WARegistry allGeneralInstances do: [:ea | ea

To prevent the image growth, you may want to execute the above
every now and then.  

You may also want to give more memory to VW. The default is 160MB, a bit
for a Seaside server.

DefaultMemoryUpperBound := 500 * 1000000. "500MB"
DefaultGrowthRegimeUpperBound := 100 * 1000000.  "100MB"
DefaultFreeMemoryUpperBound := 50 * 1000000. "50MB"
ObjectMemory installMemoryPolicy: self new setDefaults.
