Pipes and queues are two different things; a pipe simulates a

No you don't. I'm using pipes without queues extensively to simulate
WANs without bothering with any
ny further packets written to that pipe during that
time will be dropped if they can't be placed on a queue. The
practical throughput depends on the number of queue slots available
and the number of writers. I suggest you do some reading on queueing
theory for the gory details.
