I read your article and tryed it, but it still hangs on the handler and it
does not return cleanly. The other problem is that in your workaround you
wait until the child process is finished, in my program the child process
is still running and raises a signal at intermediate points in the program
so I can't check for a SIGCHLD. The question is should I drop the signal
approach to update forms from a child process and use a socket instead, if
so any example code out there doing this.

Thanks
Mark
