communication between worker processes

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 ( ), 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.
