[Click] Weird behavior under OSX Snow Leopard...

[Nicholas Weaver]

I'm seeing some very weird behavior under OSX on FromDevice...

The very simple code:
FromDevice(en0, PROMISC true) -> Print("en0") -> Queue -> ToDevice(en1);

What happens is no packets are received by the Print command until  
some internal buffer in the FromDevice fills up, and then they are all  
delivered at once in a big burst, through the queue, and out the en1  
interface.

Suggestions?
