If you mean by "value of an item" the value in the database: I suggest
you create an updater agent instead, shared by all the threads. While
each thread is in a transaction, it can `send' an action to update the
database to this agent. Agent sends are queued by the STM, so you can
be sure only one update happens, and only if a transaction succeeds.
If you mean to mutate the list of maps, you can't do that.

Not sure what this means. Futures are IDerefs...
