<issue_to_address>
No validation is performed on the provided capacity value.
Validating the `capacity` parameter can prevent issues from zero or excessively large values, reducing the risk of unexpected behavior or resource exhaustion.

<issue_to_address>
The spawned task's result is not checked for panics or errors.
Consider matching on the JoinHandle's result to handle panics gracefully, rather than allowing them to propagate.
