[tac_plus] opt_G broken again :(

[John Payne]

The opt_G timeline:

First patch: http://www.shrubbery.net/pipermail/tac_plus/2007-October/000158.html
Second patch to fix defunct processes: http://www.shrubbery.net/pipermail/tac_plus/2007-October/000163.html
Third patch to make it work: http://www.shrubbery.net/pipermail/tac_plus/2008-June/000246.html

Unfortunately, the third patch has started causing defunct processes  
again.

Now I'm really confused :)
