nginx 0.6.10
*) Feature: the "open_file_cache", "open_file_cache_retest", and
"open_file_cache_errors" directives.
*) Bugfix: socket leak; bug appeared in 0.6.7.
*) Bugfix: a charset set by the "charset" directive was not appended to
the "Content-Type" header set by $r->send_http_header().
*) Bugfix: a segmentation fault might occur in worker process if
/dev/poll method was used.
