What's critically important is that the program must keep running, and 
must not "put itself into the background" or "daemonize itself".

What's also important is that the TERM signal will actually cause the 
process to shut down. A few badly behaved programs don't do that - mysql 
in particular.

It's common practice to have programs log to stderr rather than via 
syslog.
