Rendezvous are a nice way to communicate between tasks. It was the only
way in Ada83, but it's still very convenient when tasks want to talk to
each other.
If you communicate through global variables, you'll still need a basic
synchronization for the main task to know when the data is available.
This could be as simple as including the server tasks in a block
statement: when the main program leaves the block, the local tasks are
necessarily terminated, and therefore data are stable.
