Re: Re: PHP hangs when exec'ing SSH

Ah. Well, then my bug report is probably of no matter. Even looking 
further into SSH's options, there's something for controlling the TTY 
allocated for SSH, but it only controls what TTY SSH allocates, there is 
no means for turning tty allocation off completely. I was still holding 
out some hope that this was my system configuration, and not something 
fundamental in how PHP or worse- SSH acted.
