But won't TCP still fill up its receive queue as fast as it can? I suppose
you could _deliberately_ only read a certain number of bytes rather than
everything available to keep the queue nearly full.

But anyway determining how much to wait for is very awkward indeed as you
have to know the physical bandwidth of the connection, which will change all
the time as use is shared. It would also probably lead to oscillating around
the correct value and for most people it is not acceptable for it to be
slower than it could be - any bandwidth determining step would need many Kb
before coming even close to an estimate.

Just my 2p
