mac os x buffering packets?

Gentle people,
   Apologies if this a known problem.

   On mac os x 10.3.4, using libpcap-0.8.3, opening pcap with
pcap_open_live(dev, 96, 1, 1000, errbuf)  and reading packets with
pcap_loop (pd, 1, callback, user), packets are queued until some
magic number (looks to be 200) of packets is reached, and then I get
them all.  This can take however long it takes for this threshold
to be reached (I've waited an hour).

   Anything that can be done to get packets a little sooner?

Carter
