As far as I can tell from my experimentations, this only works because
Test here is a procedure. The code I linked on github a few posts ago
also works fine that situation, since procedure-wide Cron_Entry objects
are finalized, and when the last one is finalized the tasks terminates.
The problem I'm trying to work around is when your X here is declare in
a package rather than a procedure:
with Workers; use Workers;
package Test_Library is
procedure Hello;
X : Manager;
end Test_Library;
with Ada.Text_IO; use Ada.Text_IO;
package body Test_Library is
procedure Hello is
begin
Put_Line ("Library procedure called");
end Hello;
end Test_Library;
with Ada.Text_IO; use Ada.Text_IO;
with Test_Library; use Test_Library;
procedure Test_Main is
begin
Hello;
delay 5.0;
Put_Line ("Good bye!");
end Test_Main;
Now there you get the catch-22 situation I'm hoping to solve (or failing
that, document).
Thanks for your help,
Natasha
