miyagawa/Plack — Issue #272: HTTP::Server::PSGI returns an undef writer callback when writing headers failed
Author: miyagawa

HTTP::Server::PSGI passes an undef to the application when writing HTTP headers failed in the streaming mode.

```
214 $self->write_all($conn, join('', @lines), $self->{timeout})
215 or return;
```

I just can't tell if it 's a bug since this is unspecified in the PSGI specification but it's not the optimal since the caller application will eventually die out by calling undef as a sub reference.
