[bind10-dev] Shutdown fix for bind10 (BoB) process

[Shane Kerr]

All,

After seeing some complaints about processes not exiting when BIND 10
shuts down, I had a peek at the shutdown routine from the boss process,
and it looks like someone (by which I mean "me") refactored it in a way
that didn't insure everything exited. Yes this means that tests for this
are really needed - sometime before the next release certainly!

Anyway, I've committed a fix for this in the trunk, so if you run from
there everything should terminate properly - or at least should get some
termination (SIGKILL for example).

Still to do is using process groups or something like that so a
termination signal can be sent to all decedents of the boss process, but
we don't have any such processes yet, so that can wait.
