See my other mail: I want to transmit UDP packets using full link
bandwidth, and it cannot be acheived on NetBSD because:

- If I don't sleep between sends, the queue get full, I get ENOBUFS, I
have to retry sending. And in the meantime the network interface
consumed all the data on the queue. The queue is empty and the network
is unused for some time.

- If I sleep between send, or even if I do a single system call, the
interface consume packets faster than I add them. The queue is empty and
the network is unused for some time.
