If Google is really interested in preventing the exploit you mention, 'twould be easy to make it at least uncommon enough that I wouldn't be much worried about it.
All they'd have to do is:
- Not provide ads based on the name or email address of the sender/recipient.
- Not display unapproved ads in emails.
Since Google already eventually looks over all keywords being targeted by their advertisers, that shouldn't be any big deal to actually implement. Of course, one reason for the large amount of advertisers Google has on board is 'cus of how ads go live instantly, but I think advertisers will be happy enough if their instant gratification is limited to web search results, etc. Of course, Google might not be interested in cutting a bit of their ad revenue in that way.
