*	use signalfd to stop on SIGTERM	Egor Tensin	2023-06-13
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Is this an overkill? I don't know. The thing is, correctly intercepting SIGTERM (also SIGINT, etc.) is incredibly tricky. For example, before this commit, my I/O loops in server.c and worker.c were inherently racy. This was immediately obvious if you tried to run the tests. The tests (especially the Valgrind flavour) would run a worker, wait until it prints a "Waiting for a new command" line, and try to kill it using SIGTERM. The problem is, the global_stop_flag check could have already been executed by the worker, and it would hang forever in recv(). The solution seems to be to use signalfd and select()/poll(). I've never used either before, but it seems to work well enough - at least the very same tests pass and don't hang now.

\| \| \| \| \|	pthread_attr_setsigmask_np is only available since 2.32, which is too modern.

*	worker: allow graceful shutdowns	Egor Tensin	2022-08-26
	Well, maybe "graceful" is a strong word, but now you _can_ do ./server & ./worker & ./client ci_run URL REV && kill "$( pidof worker )" and the worker will wait for the CI run to complete.
