[RFC PATCH 0/2] daemon: tracking childs without signals

This is a minimum POC of what could be done to remove signals when
handling children in git-daemon.

The advantage is that it is at least portable to *NIX systems, unlike
using a Linux specific API like pidfd which also allows collecting
status from children through fds.

It has to do some innefficient management of the fds array that is
given to poll, and wouldn't work as a general solution, since the
children could close the pipe() used for tracking unintentionally,
but since we control both sides in this case, that might not be a
problem.

Carlo Marcelo Arenas Belón (2):
  run-command: add a pipe() write end to childs
  daemon: poor man's pidfd like POC
