Pool is used to submit asynchronous tasks without waiting for their completion.

Create a new pool.

running pool returns whether it's possible to submit tasks to pool

task pool ~f submit f to be done in pool. Errors raised pool will not be raised in the current fiber, but inside the Pool.run fiber.

If running pool returns false, this function will raise a Code_error.

stop pool stops the pool from receiving new tasks. After this function is called, task pool ~f will fail to submit new tasks.

Note that stopping the pool does not prevent already queued tasks from running.

stop pool subsequent calls to stop ignored. In other words, this function is idempotent

run pool Runs all tasks submitted to pool in parallel. Errors raised by such tasks must be caught here.
