--- Comment #1 from kinke <kinke at gmx.net> ---
Pardon me, but isn't this to be expected? Creating a thread per iteration would
be an absolutely inacceptable overhead in many cases. From the std.parallelism
docs:

"After creation, a Task may be executed in a new thread, or submitted to a
TaskPool for execution. A TaskPool encapsulates a task queue and its worker
threads. Its purpose is to efficiently map a large number of Tasks onto a
smaller number of threads."
