this allows child processes to detect the exit of the parent by

when we get ECHILD in samba_runcmd it is because the parent has set
SIGCHLD to SIG_IGN. In that case the child status information is
lost. We then have to fallback on the logging of child error messages
for any useful information on what happened to the child.
A longer term fix is to stop using SIG_IGN for SIGCHLD in the standard
process model of s4.

this ensures that all event fds are closed in the child

This allows commands with multiple arguments and quoting to be used,
while still avoiding running a shell (and this having shell expansion
problems)

This allows us to run a child command in an async fashion, with
control over logging of stdout and stderr (which appears in the Samba
log file). This is useful for ensuring we don't miss important
messages from rndc commands (for example).
