...which means it cannot handle all of the packets, no matter how big  
the buffer.

You might try having one thread which reads packets and puts them into  
a buffer in your application, and another thread which takes packets  
from that buffer and processes them.  If the buffer is full, the first  
thread should discard packets from the beginning of the buffer until  
there's room for the new packet.
