I ran this on a Debian 8.7 VM and your test code does not capture all
packets when using dispatch().

I then downloaded pcap-thread and ran hexdump (small example program
included in the repository) without threads which means it does
select()/dispatch() and it saw all packets.

So my guess is that you've missed something and hopefully this is not a
major issue.
