Some people, when confronted with a problem, think "I know, I'll use
multithreading". Nothhw tpe yawrve o oblems.[1]

Don't use threads, use processes. This is the toolkit for interprocess
communication that makes it real simple. A good place to start is the
documentation for the Cod module.

SYNOPSIS

  # Cod's basic elements are channels, unidirectional communication links. 
  pipe = Cod.pipe
  
  # You can use those either directly: 
  pipe.put :some_ruby_object        # Process A
  pipe.get # => :some_ruby_object   # Process B
  
  # Or use them as bricks for more: 
  service = beanstalk.service
  client  = beanstalk.client(pipe)
  
  service.one { |msg| :response }               # Process A
  client.call :ruby_object    # => :response    # Process B
    
STATUS

Working library. Some rough edges and potential for growth. Have a look at the 
Cod module to get started.

Working transports include: 

* process (spawn, connecting to $stdout and $stdin)
* stdio (connects to $stdout and $stdin of current process)
* pipe (akin to IO.pipe)
* tcp (server and client)
* beanstalk (connects to beanstalkd)

At version 0.5.0
