Summary: ruby ( v183) bcc32: using Socket.new with timeout -> files not closed

Initial Comment:
I use ruby 1.8.3 (2005-07-11) and compiled it with Borland bcc32 v5.5.1 (W98)
and v5.6.4 (Win XP).
If Socket.new is interruptet then I run out of filehandels.
In W98 I can't close sockets anyway.
If I use ruby-1.8.3-preview1-i386-mswin32 it works but this version it is not stable for me. If I mix mswin and borland vcl-dll's (over Win32API) it crashs very often.
It is a bcc32 problem?

Example:

# bcc32 v5.6.4 Win XP
# if the connection is broken this program
# end up with something like
# - socket(2) : Too many open files (Errno::EMFILE)

# additional problem in W98 (bcc32 v5.5.1)
# close every time fails with:
# eth_mini_test.rbw:32:in `close': Unknown Error (Errno::ENOTSOCK)

require 'socket'
require 'timeout'

def  mkConnection(ip,port)
  begin
    @sok.close if @sok and not @sok.closed?
    timeout(0.5) do
      @sok = TCPSocket.new(ip,port)
    end
  rescue Exception
    if $!.kind_of?( Timeout::Error)
      print '.'
    else
      raise
    end
    STDOUT.flush
    sleep(0.5)
    retry
  end
end

mkConnection('192.168.123.223',3000)

p @sok
if @sok
  p @sok.closed?
  @sok.close
  p @sok.closed?
end
