I need a very fast IPC channel between two processes. One draws packets
from the network, and the other analyzes them.
My first thinking is that I'd like them to be decoupled so I minimize
the chance of packets being dropped by the packet grabber (although that
might be a brain dead decison--see  below).
Anyway, I'm wondering two things:
1) Is there way to check for a bandwidth limit on a loopback (PF_UNIX)
2) Does using socket based IPC exhaust network packet buffers? If so,
I'd be exacerbating the very problem I'm trying to avoid by using
Checking Stevens TCP v2 now...

different *u*x behaves better for this application.
