I was looking at an issue in this area, it seems like the
corresponding code in ap_lingering_close is not so picky about
apr_socket_recv return code. It seems like we could continually get
ECONNABORTED/ECONNRESET back and not take the socket out of the ring
until the timeout elapses.
I'm wondering if the test should be APR_STATUS_IS_EAGAIN(), and
anything else that isn't success means we no longer need to linger?
