While trying to verify tests previously excluded in Gentoo (gentoo/gentoo@b9d1c7a) I noticed that ParallelMultiSearcherTest & SortTest would work, but hang in ~ThreadPool() on threadGroup.join_all(), preventing the test executable from terminating cleanly. Stopping the io_context makes join_all() work immediately.
