- as far as i understood the netgraph docs, they also use function calls
and _no_ message queues for interlayer communication. So going
to netgraph would not solve the mentioned problem. BTW: i once
asked Terry about the queue/function tradeoffs when that was
discussed on the mailinglist and got no reply.
Having worked on both function call and queued netgraph like
software I have to agree that function call is a major design
bug in netgraph.
I'm sure netgraph uses direct call to get speed. But in DEC we
benchmarked queuing vs. direct call and there is no advantage.
On the other hand the queuing gives many advantages.
Very few reentrancy problems.
Never overflow the stack.
Simpler software - faster in design, implementation and debug
