Most of that is true.  However, I found it to be a problem with firefox
specifically - in that firefox waits for the 75 second timeout.  Forced
me to switch to opera :)

It looks like it will be fixed in the next version of mozilla, though:

The quickest workaround is to add 
::0                     ad.doubleclick.com
::0                     ad.doubleclick.net
to /etc/hosts (not a bad thing to keep in there, really).
