How might I be able to send a message or (custom) event to some given
worker process? I am storing pointers to requests (and the workers that
processed them) in shared memory for a module (
http://github.com/slact/nginx_http_push_module ), and need to alert said
workers to respond to said requests, from the context of a location
request handler in a module. (maybe using ngx_channel stuff?)
I'd really appreciate any suggestions.

Thanque,
