Description
We are using resty to run some long running processes - basically a while true loop that consumes messages from a message queue and then make some http calls for each message.
When sending a QUIT signal to resty, it correctly propagates the signal to the underlying nginx process.
Is there any way for my process to know that we have received that signal, so that we can exit for while loop, expire the resty timer and complete graceful shutdown ?
Thanks.

Research direction
Start by tracing how resty handles QUIT signals and how it propagates them to the underlying nginx process. Then inspect the timer lifecycle and determine how a long-running user loop could observe shutdown; done means the loop can stop, the timer can expire, and shutdown completes gracefully.
