title: How can you access a serial port from two different processes (Python)
body: <p>I would like to use multiprocessing (to avoid GIL issues on multi core machines) and have a read process and a write process using the same serial port.  Is that possible?  If so, how do I get the port acquired and then how do I get the child processes file objects that they can use?</p>
  
  <p>Edit -- This needs to work on Windows, but Mac and Linux would also be nice.</p>
