[Interest] Fastest way to send a signal to one of children processes

[Николай Шатохин]

Hello.

I have one main process and many children processes that controls
TCP-connections with clients (For example, one million). Each child process
can send signal to main process with id of another process. So, server must
to send data to this process. How to do this quickly? Now, I send signals
to each process and they check id in signal with their ids.

Best regards,
Nick
