As far as I know, in the event of a disconnect, Apache will send a
SIGTERM to the child, and then, if needed, wait up to approximately 3
seconds and send a SIGKILL. Your CGI could handle the SIGTERM and do
any required cleanup. It could also leave behind a long-running process
using the "at now" command.
