My thanks to everybody who replied, both here and by mail. Several people
pointed out that I said t_listen when I should have said t_bind - sorry,
my fingers were running faster than my brain....
However, nobody has answered the question that I was trying to ask. I can't
have made a good job of the question :-)
Why does this connection queue have to be handled by the kernel? Why couldn't
the application just open and initialise for listening (not in the BSD syscall
sense) as many transport endpoints as it's queue needs to be long?
