Proper setting of read->eof in pipe code. Setting read->eof to 0 seems to be just a typo. It appeared in nginx-0.0.1-2003-10-28-18:45:41 import (r164), while identical code in ngx_recv.c introduced in the same import do actually set read->eof to 1. Failure to set read->eof to 1 results in EOF not being generally detectable from connection flags. On the other hand, kqueue won't report any read events on such a connection since we use EV_CLEAR. This resulted in read timeouts if such connection was cached and used for another request.
