kdb may enter spontaneously (BUG(), etc) so it can be useful if one
returns from an overnight test run to know how long things survived.
It would almost certainly be possible for a skilled user to reconstruct
the time of death. Having said that, one of the things you can do with
kdb (although I admit *I* have never done it) is leave a macro command
in the hands of an unskilled user.
Short summary: no puppies would die, but perhaps some might go hungry
for a little while when their owner is late home?
