def _fork
  pid = super

  AtForkMonkeyPatch.run_at_fork_blocks(:child) if pid == 0

  pid
end

#daemon(*args) ⇒ Object

A call to Process.daemon ( rubyapi.org/3.1/o/process#method-c-daemon ) forks the current process and keeps executing code in the child process, killing off the parent, thus effectively replacing it. This is not covered by ‘_fork` and thus we have some extra code for it.
