The subject of my post pretty much sums up my question: What happens when PassengerMaxPoolSize is reached?

For Example:

PassengerMaxPoolSize is configured to 40 based off our system specs

What happens if all 40 sessions are active (processing a request) and our load balancer passes another session to this particular web server? This would send a 41st session to be processed without an available Passenger process.
