two threads reading from the same socket at same time produces race condition whichs locks interpreter

code to repo:

require 'socket'
# if this ever stops printing we're screwed
Thread.new{loop{p 1;sleep 0.5}}

s = Thread.new do
  cli = TCPServer.new(3020).accept
  loop { cli.write 'hi' }
end

sock = TCPSocket.new('localhost', 3020)
2.times do
  Thread.new do
    loop { sock.readpartial 1024 }
  end
end

s.join
