This is some AI generating a Perl preforking HTTP server.

use IO::Prefork;
use LWP::UserAgent;
use Time::HiRes qw(gettimeofday);
use Socket;

my $prefork = IO::Prefork->new();
$prefork->listen(4000, '127.0.0.1');

sub handle_request {
    my ($req, $env) = @_;
    my $now = gettimeofday();
    print STDERR "Request received: $req\n";
    
    # fork a new process for this request
    my $pid = fork();
    if ($pid == 0) {
        # child process, handle the request
        eval {
            $prefork->handler($req, $env);
        };
        if (WANTED_EXIT_CODE) {
            exit(WANTED_EXIT_CODE);
        }
    } else {
        # parent process, wait for child to finish and handle its result
        my $child_exit_code = wait();
        die "Child process did not exit cleanly: $child_exit_code" if ($child_exit_code != 0);
        
        # send the result of the request back to the client
        my $response = $prefork->result;
        print STDERR "Sending response back to client\n";
        print $response;
    }
    
    # log the time it took to handle this request
    my $elapsed_time = $now[3] - $now[2];
    print STDERR "Request processed in $elapsed_time seconds\n";
}

$prefork->process({ 'id' => 1, 'cmd' => sub { exec("/usr/bin/php-fpm")->out(0); } });

First problem: IO::Prefork doesn't exist. And that functionality wouldn't go in the IO:: namespace anyway.

Second problem: It seems to want to do the forking in handle_request(), which would imply it's forking during each request, not before requests, as asked. I say "seems" because handle_request() isn't used anywhere, anyway.

The cherry on top is the last line, where it just execs php-fpm anyway.
