HTML filtering

[josh hoblitt]

A blocking call to flock before calling accept on a HTTP::Daemon object
and then releasing doesn't seem to solve the problem.  But calling sleep
1 after an accept seems to make the problem go away as long as your
making serialized connections.

This is a snipet from HTTP::Daemon.  I suspect I need to add some
locking in there but I'm not sure exactly what SUPER is.  Any ideas on
what needs to be done?

sub accept
{
    my $self = shift;
    my $pkg = shift || "HTTP::Daemon::ClientConn";
    my ($sock, $peer) = $self->SUPER::accept($pkg);
    if ($sock) {
	${*$sock}{'httpd_daemon'} = $self;
	return wantarray ? ($sock, $peer) : $sock;
    } else {
	return;
    }
}


Thanks,
