Well, when Apache has handed control off to PHP, it is up to PHP to decide
what to do when a connection is aborted. Currently Apache sets a flag
which PHP catches and initiates the request shutdown calling all the
necessary cleanup functions.

There are other cases when Apache tells PHP to stop. Like when someone
terminates the httpd process, or sends a HUP to it. For those cases PHP
has registered a cleanup function with Apache which Apache then will call.
