Description
For example, running the distance matrix example in the RcppParallel gallery with TBB (but not tinythread) as the backend results in unreleased threads after the program finishes. Tested on both macOS and Linux platforms -- I am assuming this is broadly replicable, but if not, am happy to provide specifics.
Is this behavior intentional and if so, is there an accepted way to release the threads?

Research direction
Start by running the RcppParallel gallery's distance matrix example with the TBB backend on macOS or Linux and compare it with tinythread. Investigate the TBB thread lifetime and shutdown behavior; done means determining whether unreleased threads are intentional and identifying or documenting an accepted release mechanism.
