Killing zombie children :-)

[Conrad Steenberg <conrad srl caltech edu>]

Hi all

I have a gtk app that forks off a child process to handle some I/O, via
pipes. While trying to make the arrangement more robust, the parent
gets signalled when the child dies, and can successfully refork and
continue. 

My problem is this: the original child hangs around as a zombie process.
What should I do to prevent this? All pipes connected to the zombie child
are closed upon the receipt of the SIGCHLD, and all events monitoring I/O
from/to the child gets cancelled with gdk_input_remove().

Any more informed persons with a clue?

Cheers

Conrad
