open-tcp-server-socket returns a port. You never close it. You only
pass it to read-line, once.
The manual says close-tcp-server-socket does not affect existing
connections. They will not be closed until Scheme exits (unless the
client closes its end).

Hey, every paren is sacred! You did not remove an "extra" paren. You
removed a function call!
This is a function call: (proc arg1 arg2)
This is two function calls: ((proc arg1 arg2)). The first (inner) one
had better return a procedure expecting zero arguments!
