PR_SET_PDEATHSIG is not fully reliable, so instead maintain a pair of
...
AF_UNIX SOCK_STREAM sockets between the master processes and each subprocess,
and poll for the HUP event.
At the same time, be specific about the events that are checked in epoll
when dispatching on an event.

Bound the subprocess lifetime using prctl(PR_SET_PDEATHSIG, ...).
...
The pipes wouldn't do this job anymore because they were unused and thus
never performed writes that would generate SIGPIPEs, so the pipes are
removed, too.

Use a socketpair rather than a pair of pipes for communication between
...
ndhc and ifch, similar to sockd. A single pipe is also maintained so
that SIGPIPE can bound the lifetime of an orphaned ifch process.
