[fpc-devel] Suggestion: reference counted objects

[Boian Mitov]

BTW: Please note that since you can keep adding executions to the task, it 
can be done in nested loops, as well as in function calls thus doing fully 
fledged parallelization.
The executor also can be single thread, unlimited threads, self balancing, 
or limited pool depending on the specific instance, so a very fine control 
can be exercised over the execution, as well as it can be changed 
dynamically by code, thus sometime executing the code with one executor and 
other times with another, based on the specific needs.

Adding simple parallel loop lacks any of this power, and only serves very 
specific cases.

Here is example from our implementation:

for AIndex := 0 to Length( AList ) - 1 do
  AExecutionTask.Add(
      FExecutor.Execute(
          TDelegate.Capture<Integer>( AIndex,
              procedure( ALocalIndex : Integer )
              begin
                Sleep( 1000 ); // Simulate thread busy doing time consuming
task
                AList[ ALocalIndex ] := ALocalIndex * 2;
              end
            )
        )
    );

AExecutionTask.WaitFor();
