pcap_loop() not returning after pcap_breakloop() until another packet arrives

["Richard Hansen" <pcap-ri () scientician org>]

Hi all,

I have one thread that sits in pcap_loop() and another thread that calls pcap_breakloop() when it is time to shut down. 
 My code works well on Windows (WinPcap 3.1).  On Linux (libpcap 0.9.4, kernel 2.6.16) the pcap_loop() doesn't return 
after calling pcap_breakloop() until another packet arrives.  Is this expected or proper behavior?  How can I tell 
Linux to return from that readfrom() call that it's blocking on?

Thank you!

Richard
