std.parallelism.taskPool daemon threads not terminating

[Moritz Maxeiner via Digitalmars-d-learn]

So, I am probably overlooking something obvious, but here goes:
According to my understanding of daemon threads and what is 
documented here[1],
this following program should terminate once the druntime shuts 
down, as the thread working on the task is supposed to be a 
daemon thread:

import std.parallelism;

void main()
{
        taskPool.put(task({ while(true) {} }));
}

The actual behaviour (with dmd 2.071 and ldc2 1.0.0), however, is 
that the program keeps running.

In contract, this behaves as expected:

import core.thread;

void main()
{
   with (new Thread({ while(true) {} })) {
       isDaemon = true;
       start();
   }
}

Commenting out setting the isDaemon property will achieve the 
same behaviour as the taskPool example. Is this the intended 
behaviour of taskPool (because it does have isDaemon set)?
