> Add Window abstraction to Trinidad. Currently, Trinidad knows nothing of the
> separate browser Windows that make up a browser session. This causes weird
> problems. For example, the state management token cache is shared across all
> of the active windows with a simple LRU. If the user opens up two windows
> and operates on one window long enough, he will cause the token state for the
> original window to be purged. When the user switches back to the original
> window and POSTs back, the token won't be found, Trinidad will assume that
> this is because the session expired, and the user will be given an error.
> Adding the concept of a Window and a Window lifecyle opens up the following
> capabilities:
> 1) Correct handling of per-window UI state by segregating tokens by window
> 2) Early clean-up of UI state by aggressively purging state for closed windows
> 3) Applications can manager per-window state by listening for window
> lifecycle events
> 4) Sessions can be cleaned up earlier by terminating the session when the
> last window in the session is closed
> 5) A window scope can be implemented to ease using per-window state with EL
> 6) A window manager implementation can hide the details of handling control-N
> in the browser
