Maybe the http server hasn't closed it's read side of the connection,
only the write side?

Clients are supposed to monitor the read side of the tcp link
continuously, that allows the server to close at any time or to send a
failure response before an entire request is sent by the client.

I don't know how you'd handle that with luasocket's http, but it might
be something to look into.
