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&period; If `metricsRegistry` is 0, `bdlm&colon;&colon;MetricsRegistry&colon;&colon;singleton()` is used&period; Optionally specify a&apos;basicAllocator&apos; used to supply memory&period; If `basicAllocator` is 0, the currently installed default allocator is used&period; The name used for created threads is `threadPoolName` if not empty, otherwise &quot;bdl&period;FixedPool&quot;&period; The behavior is undefined unless `1 &lt;&equals; numThreads`&period; Note that the actual job queue capacity can be obtained using `queueCapacity`, and may be more than `maxNumPendingJobs`&period;
