cc8a88c059 Remove use of "%n" 
https://cvsweb.openbsd.org/src/lib/libc/stdio/vfprintf.c?rev=1.79&content-type=text/x-cvsweb-markup

I think this is silly, as I've said elsewhere, and it's a shame
because that was clearly the best way to write this. Oh well.

da4ccb18f4 Check signals first in the loop 
Signals need to be checked first in the loop to catch any that were
delivered between setting up the signals handlers and entering the
loop, i.e. in the time it takes to initially start each of the
services.

7769a4f6e9 Log a message when stopping a service waiting to restart 
It's a little annoying to have to special-case this, but otherwise there
is no confirmation in the log that the restart won't still happen.

5b1a5f2876 Do not increment signals 
No need to do a read and a write... and it's declared volatile so maybe
that's even worse? I don't even know, but there's no point.

d90a43d948 Humanize milliseconds if interval is less than 1s 
The intervals are configurable in milliseconds so humanize should be
able to display at that precision.

0d7303e75f Parse config later 
This is just to keep the list of open file descriptors tidier, since
parsing the config creates many pipes.
