After the script makes its announcement, it uses
start a long job, then exits.
Here is the cgi script, and here is the script that it calls.
We execute this by calling unhook.cgi.
You see the problem: the server waits until the long job is completed before it sends anything back to us.
The way around this is to use nph-unhook.cgi.
