    We had accidentially grown two fake ones: one for backtrace.c, and one
    for sandbox.c.  Let's do this properly instead.
    
    Now, when we configure logs, we keep track of fds that should get told
    about bad stuff happening from signal handlers.  There's another entry
    point for these that avoids using non-signal-handler-safe functions.
