Looks like it would have worked well enough with SIGTERM.

Probably more helpful in run_cmd()

Possibly.  Both bits of signal handling just exit the program, which 
isn't normally what I think of SIGHUP for.  You already have SIGTERM 
where you need it (in run_cmd()), so maybe the author didn't think it 
useful elsewhere.  And of course, none of this really matters much on 
Windows.
