     On UNIX systems, the default signal sent by kill is SIGHUP.  Is that
default signal different on LINUX systems?  A SIGHUP will not result in
tor shutting down unless it discovers an error upon rereading torrc.  On
a UNIX system, "kill -TERM <pid>" should be used.  On FreeBSD systems,
tor puts its pid into a file called /var/run/tor/tor.pid, so a command
like "kill -TERM `cat /var/run/tor/tor.pid`" will initiate the shutdown
sequence, but the tor port in FreeBSD also establishes a script called
/usr/local/etc/rc.d/tor, so "/usr/local/etc/rc.d/tor stop" will do it, too.
Changing "stop" to "start" does what it says, and "restart" combines "stop"
and "start".  I'm surprised a LINUX installation doesn't have some
equivalent setup, though with different path names to the files involved.
