Yes. That's correct.

Perhaps with code something like that:

require "socket"

threads = ThreadGroup.new;

server = TCPServer.new('127.0.0.1',5190)
while 
  Thread.new(session = server.accept) {|mySession|
    threads.add(mySession)

    while mySession
      #do all my business
      
      if event_triggered then do
        threads.list.foreach do
          |thread|
          thread.kill
        end

      end
      sleep
    end
  }
 end
