> This is an umbrella bug for a number of changes aimed at reducing the overall memory
footprint of a Tapestry page.  Tapestry pages have been seen to be quite large in some production
sites, and the shared-instance strategy introduced in 5.2 is still insufficient. A significant
amount of space is consumed using Maps and Lists (for bindings, of sub-components, etc.) in
a way that is optimized for a smaller code base and efficient read access, even though most
of the information is only read when a page is first loaded, and is rarely needed or accessed
after that.
