Hello,

The previous patch was not working. The reason is that, when a process
is forked and before execv is called, it shares the parent signal
handler.

So when sending a SIGTERM to the child process, we are stopping
root-service, if the signal is received before the child has forked.

The work-around here is to save the installed SIGTERM handler and reset
it. Then, after forking, the parent can restore the SIGTERM handler. The
child will use the default SIGTERM handler that terminates the process.

WDYT?

Thanks,

Mathieu
