libpcap & poll()

["Aaron Turner" <synfinatic () gmail com>]

I've been told by an end user under Linux 2.6.x at least that, he's
seeing very high CPU utilization numbers with tcpbridge which uses
libpcap to read packets.  Sounds like the cause of the issue is that
I'm using poll() to determine when to read from libpcap.  I'm using
poll() because my code listens on multiple interfaces, hence I need a
way to look at multiple pcap handles.

Questions basically boil down to:
1) Is this expected?
2) Is there a better way?

Thanks,
Aaron
