New Revision: 4916
URL: http://trac.nginx.org/nginx/changeset/4916/nginx

Log:
Upstream: better detection of connect() failures with kqueue.

Pending EOF might be reported on both read and write events, whichever
comes first, so check both of them.

Patch by Yichun Zhang (agentzh), slightly modified.
