A common pattern in our old code was to have a serializing tasks.
That is a task that today would have been written as a protected object.

It held the data in local structures - perhaps in its body or in a
package body that only this task could access.

Then, the rest of the tasks as well as the main thread,
accessed the data via the serialization task.
