Anywhere in your normal app dispatch path, just initialize the
lock during application load (regardless of preload value)
def initialize(...)
@lock = Mutex.new
@old_quit = nil
end
def call(env)
unless @old_quit
@lock.synchronize do
@old_quit ||= trap(:QUIT) do
app_specific_quit
@old_quit.call
end
end
end
...
end
