I don't know the answer for sure, but I believe it to be a significant 
number; there are pipes created for each channel's audio, and also for 
alerting the channel driver of events. If the channel uses RTP, then a 
socket will be created for that as well. There could be 4-6 fds used for 
a channel in some cases.
