We already stash the associated FD for reporting at startup and
don't need to call `fileno' again. Found via manual code
inspection while considering the effort to make async {forward}
from PublicInbox::HTTP more like the generic long_response API
and {long_cb} field used by IMAP/NNTP/POP3.
delete $self->{long_cb};
$self->long_response_done;
my $elapsed = now() - $t0;
- my $fd = fileno($self->{sock});
$self->out(" deferred[$fd] done - %0.6f", $elapsed);
my $wbuf = $self->{wbuf}; # do NOT autovivify
requeue($self) unless $wbuf && @$wbuf;
