Read buffer size and flush threshold tuning (v2)

Thanks for the details.

I was able to reproduce and the issue came from the socket timeout set to zero
in ap_core_output_filter(), and later used for apr_poll() in
send_brigade_blocking() (i.e. poll() was asked for immediate POLLOUT
availability and timeouted otherwise, e.g. not on localhost...).

Fixed in this v2 by passing the (original) timeout to send_brigade_blocking().
