coarse-grained tasks. This policy can be specified by the `schedule` argument. The
execution of the loop waits for the evaluation of all iterations.

Tasks spawned by `@threads` are scheduled on the `:default` threadpool. This means that
`@threads` will not use threads from the `:interactive` threadpool, even if called from
the main thread or from a task in the interactive pool. The `:default` threadpool is
intended for compute-intensive parallel workloads.

See also: [`@spawn`](@ref Threads.@spawn) and
`pmap` in [`Distributed`](@ref man-distributed).
For more information on threadpools, see the chapter on [threadpools](@ref man-threadpools).
