Both Unix-socket clients (Korban Processor, Talmudic Engine) read a
reply with a single :gen_tcp.recv/3, which returns at most one receive
buffer — 1460 bytes, measured — whatever the packet mode. A bedikah of
forty claims answered in 18 KB: the client decoded the first 1460
bytes, failed, reconnected, failed again, and returned an error with
the retry's socket still open. The single-threaded Korban Processor
then sat on that dead conversation and every later bedikah, however
small, timed out at 15 s. Live, for every caller, from the first long
output.
Clients now read until the newline (recv_line/2, 16 MiB ceiling) in
raw mode, and close the retry's socket on failure. The Korban
Processor drops a connection that says nothing for 120 s, so one
stuck client can no longer hold the door. tablet50_socket_line_test
stands up a 60 KB-line server and asks both clients. Elixir 552/0
(L3 on and off), korban 280.
