manticore request timeout for "sync" call not working

I have an implementation like this below when using manticore:

require 'manticore'
default_conf = {
  stale_check: true,
  check_connection_timeout: 15000,
  retry_non_idempotent: true,
  request_timeout: 8,
  socket_timeout: 8,
  connect_timeout: 8
}

url = 'http://localhost:60004'

client = Manticore::Client.new(default_conf)

def get_timeout_manticore(client, url)
  start = Time.now
  begin
    resp = client.get(url).body
    puts "Timeout at: #{Time.now - start}"
    puts resp
  rescue StandardError => e
    puts "Timeout at: #{Time.now - start}"
    puts e.message
  end
end

get_timeout_manticore(client, url)

python script below

import socket                   # Import socket module
import time
port = 60004                    # Reserve a port for your service.
s = socket.socket()             # Create a socket object
host = socket.gethostname()     # Get local machine name
s.bind(('localhost', port))            # Bind to the port
s.listen(5)                     # Now wait for client connection.
print('Server listening....')
while True:
    conn, addr = s.accept()     # Establish connection with client.
    print('Got connection from', addr)
    data = conn.recv(1024)
    print('Server received', repr(data))
    filename='youfilleout.txt'
    f = open(filename,'rb')
    l = f.read(10)
    while l:
        time.sleep(2)
        conn.send(l)
        print('Sent ',repr(l))
        l = f.read(10)
    f.close()
    print('Done sending')
    conn.send('Thank you for connecting')
    conn.close()

• When I run against my local server, the "request_timeout" does not seems to be used. I may be using manticore in the wrong way. Or something does not look directly observable.
