right. that part is missing in my proposal. but it can be solved by registering
an item state listener
that gets callbacks when an item state changes. If the callback is for a weakly
referenced item state,
then the serialized copy needs to be updated.

> Project: Jackrabbit Content Repository
> Issue Type: Improvement
> Components: jackrabbit-core
> Reporter: Marcel Reutegger
> Priority: Minor
>
> Currently the transient space in jackrabbit-core is held completely in
> memory. This limits the number of items that can be part of a save call. The
> memory usage for the transient space should be lowered significantly, e.g. by
> writing item states to a swap file on a disk.
