Subject: BasicSocket Problems

Everynow and then I get issues with using BasicSocket or any of its 
subclasses. I continually get errors like:

listeners.rb:136:in `recv': An established connection was aborted by the 
software in your host machine. - recvfrom(2) (Errno::ECONNABORTED)

On this one I have no clue. Should I try to resend my data?

or errors like:

Errno::EINVAL while doing a:
   socket.puts "test" unless socket.closed?

I see that if a socket gets shutdown, it will not appear closed, but you 
still can't use the socket.. is there any way to determine if a socket 
shutdown?

irb(main):001:0> require 'socket';
irb(main):002:0* s = TCPSocket.new( 'www.google.com', 80 )
=> #<TCPSocket:0x2dc41c8>
irb(main):003:0> s.shutdown
=> 0
irb(main):004:0> s.puts "/GET"
Errno::EINVAL: Invalid argument
         from (irb):4:in `write'
         from (irb):4:in `puts'
         from (irb):4
irb(main):005:0>

In my code I never manually call shutdown, but perhaps its getting 
called w/o my help?
