* For performance critical channels (storage, networking

* of time is the monitor latency - currently around 100 usecs. This

*
* A) Making the host more efficient - each time it wakes up,
* potentially it will process morev number of packets. The
* monitor latency allows a batch to build up.
* B) By deferring the hypercall to signal, we will also minimize
* the interrupts.
*
* Clearly, these optimizations improve throughput at the expense of
* latency. Furthermore, since the channel is shared for both
* control and data messages, control messages currently suffer
* unnecessary latency adversley impacting performance and boot
* time. To fix this issue, permit tagging the channel as being
