Forking process on every incoming event is terrible idea IMO. Threads are
more lightweight than processes.
Can you use threads in PHP? I am not familiar with PHP (Java developer
myself).  I can explain how I would implement it in Java.

There is one SocketReader thread and several Worker threads in a thread

"SocketReader" thread - reads data (events) from socket. When event arrives
SocketReader checks thread pool, get one Worker (if any) and makes it to
process event. If there no available Workers in a pool then event goes
directly to a EventQueue. When Worker finishes it checks EventQueue and if
there are no events in a queue Worker goes back to thread pool, otherwise it
process event from queue.
