I'm not sure what pages link to it from within the Wiki. Maybe Cliff 
Wells can answer that. I knew I'd find it quickly by googling "nginx 
signals".

The default signal for "kill" is TERM (at least it is in Linux and I 
believe in FreeBSD as well) so by default it kills the process but there 
are other signals that do not kill the process.
