- * We maintain a number of worker thread pools, to spread lock contention.
- *
- * Pools can be added on the fly, as a means to mitigate lock contention,
- * but can only be removed again by a restart. (XXX: we could fix that)
- *
- * Two threads herd the pools, one eliminates idle threads and aggregates
- * statistics for all the pools, the other thread creates new threads
- * on demand, subject to various numerical constraints.
- *
- * The algorithm for when to create threads needs to be reactive enough
- * to handle startup spikes, but sufficiently attenuated to not cause
- * thread pileups.  This remains subject for improvement.
+ * Write data to fd
+ * We try to use writev() if possible in order to minimize number of
+ * syscalls made and packets sent.  It also just might allow the worker
+ * thread to complete the request without holding stuff locked.
