work queue

The Directory Server work queue is the mechanism that it uses to keep track of outstanding requests and ensuring that they are processed in an appropriate manner. The work queue functionality is provided by an extensible API, but the default implementation is relatively simple: a queue is serviced by a number of worker thread. As long as there are free worker threads, then the queue will generally remain empty. If all worker threads are busy, then subsequent requests will be placed in the work queue so that they are processed in a FIFO manner.
