[nginx] svn commit: r4692 - trunk/src/os/unix

[mdounin at mdounin.ru]

Author: mdounin

New Revision: 4692
URL: http://trac.nginx.org/nginx/changeset/4692/nginx

Log:
Fixed segfault with poll and resolver used.

Poll event method needs ngx_cycle->files to work, and use of ngx_exit_cycle
without files set caused null pointer dereference in resolver's cleanup
on udp socket close.
