- * nels = number of elements on the queue
- * elsize = element size, presumably 4 and cacheline-size will
- *          be popular choices.
- * coid  = consumer coid, from ChannelCreate
- * pid   = consumer pid
- * pulse_code  = pulse code consumer expects
- * pulse_value = pulse value consumer expects
- * consumer_prio = consumer's priority, so pulses won't change
- *                 the consumer's priority.
- *
- * The idea is to call this function in the queue consumer,
- * and e-mail the queue pointer to the producer(s).
- *
- * The spp process / main thread allocates one of these
- * at startup; its main input queue. The spp main input queue
- * has a pointer to it in the shared memory segment header.
- *
- * You probably want to be on an svm data heap before calling this
- * function.
