Forking wiht zvterm

[Hilaire Fernandes <hilaire ofset org>]

In the following code I'm unable to get a Python interpreter running
in a zvt widget after a fork. Instead the Pyhton interpreter runs in
the terminal where the initial application was started and no windows
appears.

Looking at the childed process with 'ps axf' shows me that:

30694 ?        S      0:03 gnome-terminal
30695 ?        S      0:00  \_ gnome-pty-helper
30696 pts/0    S      0:00  \_ bash
 5730 pts/0    S      0:00      \_ [python]
 5731 pts/0    Z      0:00          \_ [gnome-pty-helpe <defunct>]
 5732 pts/2    S      0:00          \_ [python]


Any idea about the problem ?

Thanks

Hilaire
