Introduce Async::Task#defer_stop{} which can be used to implement graceful shutdown.
In a typical client server architecture, it's common for a server process to handle discrete requests. When it is time to shut down, we should try to terminate after finishing the response.
Async uses Async::Task#stop to request a sub-system to exit. Exiting while writing a response or closing a connection is more likely to cause problems for the client. By deferring stop, we enable services to implement graceful shutdown timeout.
def run_server
Sync do |task|
while request = read_request
task.defer_stop do
response = generate_response
write_response(response)
end
end
end
