Yep... that appears to be it. When setting SERVER_DEAD we
aren't resetting the pid as well. Instead of working around
that, wouldn't the most straightforward approach be to
sync setting SERVER_DEAD status with also setting pid to 0?
This could be done in ap_update_child_status() which would
also hopefully address those file-based scoreboards as well.
