Construct a thread pool with the specified threadAttributes, numThreads number of threads, a job queue with 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 threadAttributes.threadName() if not empty, otherwise threadPoolName if not empty, otherwise "bdl.FixedPool". The detached state of threadAttributes is ignored, and e_CREATE_JOINABLE is used in all cases. 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.
