[Asterisk-Dev] EAGI : Pipe saturation

[Areski]

Well, I created a script that loop all the time until that the user
hangup. With AGI, my script is not killed by Asterisk for some reasons
;/ (perhaps it's normal) 

Actually, I just tricked it on AGI, so it's work fine now, I detect the
hangup from stdin. Perhaps that was the way.

Cheers,
Areski
