# Optimization for decreasing startup time. Since Apache starts the spawn
# server twice during startup, we don't want to load the Passenger classes
# if we don't need them.
# We check whether Apache immediately closes the connection. If so,
# we exit without loading the rest of Passenger. If Apache doesn't close
# the connection within 4 seconds then we continue with loading Passenger,
# so that loading doesn't happen during the first spawn.
