Intercept UNIX signals

[albrow]

Currently, if you cause a worker pool process to quit by sending a UNIX signal (e.g. by pressing ctrl-c), it will quit immediately without waiting for jobs to finish executing. This is good behavior for testing purposes (because it lets me simulate hard failures), but ideally the process should intercept certain types of signals and wait before exiting.

+1 for this and also for making sure it works when your running in a docker container.

@epelc, thanks for your feedback. I'm targeting this for version 0.3.1. Can you elaborate on what is required in order to be compatible with docker? AFAIK there is nothing that would make it incompatible, but I'm only played around with docker a little.

@albrow I don't think anything you do would be inherit nay incompatible. I just thought it'd be a good idea to test it with docker.

I'd test that it works with docker stop and possibly docker kill. Let me know if you need any help testing.
