Async notification in Nginx

Server NGINX
1

I am writing a Niginx module that from several of worker threads
that I created by own, I need to notify Nginx’s main thread so
the main thread (single-threaded nginx) doesn’t need to poll
periodically in timer context. What would be the reliable way to
do that in Nginx? Anybody advice would be appreciated.

By browsing the source code, it seems ngx_event_t can be
used for this purpose, but looks like ngx_event_t has to be
associated with ngx_connection_t, does ngx_connection_t
have to be a socket, or a regular file descriptor will do? Is there
any forum for wrting nginx modules?
