Right, it was part of the example.

Based on your response... I think we have a problem with our interface.

cmd_allocate_channel(invocation_handle, channel, capacity_reservation)
cmd_deallocate_channel(invocation_handle, channel)

Regardless of whether we return a channel to the user, or the user specifies a desired 
channel...

How does cmd_deallocate_channel() know how much to de-allocate?  If these are hardware 
channels we are talking about (currently 2 in hardware), and I now want to deallocate my 
channel and i say cmd_deallocate_channel(blah, 1) ... I am going to deallocate all of 
channel 1 which is incorrect.  The capacity I reserved should be deallocated.

So then is it required for the requester to keep track of how much they requested to pass 
to our deallocation method?
