If you don't want your timer to delay process exit, there's "cancelable" flag:

http://nginx.org/en/docs/dev/development_guide.html#event

 | cancelable — Timer event flag indicating that the event should be ignored
 | while shutting down the worker. Graceful worker shutdown is delayed until 
 | here are no non-cancelable timer events scheduled.

When to delete event timers

[Antonio Nappa]

Hello,

I have a module which registers several events and I am using Nginx 1.12.1,
it looks like when I do a reload that the worker(s) hang and with the help
of strace I see that the events hanging are my events. I have added a
function on process exit but it does not get called (probably because of
the pending events). So my question is when should I delete the timers if
not on process exit?

Thanks,
Antonio
