    Hi mod_perl gurus,

    the following piece of code works well under a normal cgi:
        
    local(*META, *HIS_IN); # Create local handles if needed.
    $childpid = open2(\*META, \*HIS_IN, $queryString)
            or print STDERR "can't open pipe $queryString $!";

    while ($line=<META>){

    ...

    }
    close(META);
    close(HIS_IN);
    waitpid($childpid, 0);

    But it fails under mod_perl Apache/2.0.49 (Unix) mod_perl/1.99_13
    Perl/v5.8.0
    I'm not able to see any output from the open2ed command.

    Any help will be appreciated.

    PS: the original problem is that using open ("command |") the command
    remains appended as zombie. So i'm trying to switch to open2 for
    accessing waitpid.
    Any alternative solution?
