sooooooooooo. finally. The external process is started from within web2py. Which is handled by a webserver. Which ALWAYS imposes a timeout. You can't start a neverending process inside a web request. That's why long-running processes NEED to be managed OUTSIDE web2py (and why web2py provides a nifty out-of-band processor called scheduler)
