Parallel execution (CGI)

Hi! I am using Python for CGI scripting. I had the following script: #!/usr/bin/python import sys print 'Content-type: text/html\r\n\r\n' print 'starting...' sys.stdout.flush() x = 99 y = 5478 counter = 0 while counter < 1000: z = x^y counter += 1 print 'finished!' sys.std

Hello, Although posted this a few weeks ago I still have gotten much feedback so I want to put this out again and see if the response gets a bit more interesting. I have been searching on the web for a while now for a specific Python implementation of an FSM. More specifically what I am looki
