Ruby/tk slow threads?

My code opens up a text window with an entry field. The text area gets
populated with the first spurt of text from the MUD, but then doesn't
update! Is my entry field not actually sending text to the server, or
are the threads for receiving text from the MUD going slow?

require 'tk'
require 'socket'

connection = TCPSocket.new("dark-legacy.com", 9898)

frame = TkFrame.new.pack(:expand=>true, :fill=>:both)
entry = TkEntry.new(frame).pack(:side=>:bottom, :fill=>:x)
t = TkText.new(frame) do
yscrollbar(TkScrollbar.new(frame).pack(:side=>:right, :fill=>:y,
:expand=>false))
pack(:side=>:left, :fill=>:both, :expand=>true)
end

killed = false
Thread.new do ||
begin
while killed == false
inp = connection.recv(100)
t.insert(:end, inp).see(:end)
end
rescue StandardError
puts $!
end
end

entry.bind('Return') do ||
connection.write(entry.value)
entry.delete(0, :end)
end

entry.focus

Tk.mainloop

t.insert(:end, inp).see(:end) unless inp.empty?

connection.write(entry.value + "\n") # ???

Though I don't know the protocol of your server,
does the server need "Return" at end of a command line?
