The 'mmap' module can help with getting the data from 5 to 1. It requires creating a file. If it's a small amount of data, any old file will do. You may need a socket in order to wait for Process3 to join, or write a small '.pyd' or '.so' file that gives you access to your system's synchronization object. -- http://mail.python.org/mailman/listinfo/python-list
