Construct a thread pool with the specified `numThreads` number of threads, a job queue of capacity sufficient to enqueue the specified `maxNumPendingJobs` without blocking, the specified `threadPoolName` to be used to identify this thread pool, and the specified `metricsRegistry` to be used for reporting metrics. If `metricsRegistry` is 0, `bdlm::MetricsRegistry::singleton()` is used. Optionally specify a'basicAllocator' used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The name used for created threads is `threadPoolName` if not empty, otherwise "bdl.FixedPool". The behavior is undefined unless `1 <= numThreads`. Note that the actual job queue capacity can be obtained using `queueCapacity`, and may be more than `maxNumPendingJobs`.
