It depends on what Apache's doing with the 25 seconds (proxy, cgi,
reading a file, running php code, proxy).

Apache doesn't limit itself to 25 seconds of running your CGI or 25
seconds of trying to read a file from a dead network drive.

>From the manual:

The TimeOut directive currently defines the amount of time Apache will
wait for three things:

   1. The total amount of time it takes to receive a GET request.
   2. The amount of time between receipt of TCP packets on a POST or
PUT request.
   3. The amount of time between ACKs on transmissions of TCP packets
in responses.
