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)

PS: it was the first thing I said.
