when i get a html file including a line "<!--#exec cmd="ls" -->",
a child process of cgi daemon process in the server becomes zombie.
i'm using FreeBSD4.6-RELEASE and apache-2.0.39.
cgid_server() calls apr_signal(SIGCHLD, SIG_IGN), but it doesn't work
at least in my environment. i might be misoperating, anyway the patch
is attached in this mail. i haven't care about the porting issue.
so if this patch needs to modify to be suitable for other platform.
i'm sorry if this issue has been already discussed.
thank you.
