It is faster on all tests. * Add sparsely-populated multi-threaded benchmarks. * fix * fix * refactor to help thread safety analysis * Specialize WorkQueue for Closures and AnyInvocables remove unused callback storage * add single-threaded benchmark for closure vs invocable * sanitize * missing include * move bm_work_queue to microbenchmarks so it isn't exported * s/workqueue/work_queue/g * use nullptr instead of optionals for popped closures * reviewer test suggestion * private things are private * add a work_queue fuzzer Ran for 10 minutes @ 42 jobs @ 42 workers. Zero failures. Checked in a selection of 100 good seeds after merging the thousands of results. * fix * fix header guards * nuke the corpora * feedback * sanitize * Timestamp::Now * fix * fuzzers do not work on windows * windows does not like multithreaded benchmark tests		2 years ago
