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.

into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option.
