There is a way, but I find it somewhat ugly/hackish. But Shane uses it
in CookieCrumbler, so it must be good ;)

You can pass an instance to REQUEST._hold, which should be deleted 
when REQUEST gets deleted, so at the complete end of the request.

This means you can pass an instance to a class that defines a __del__
method, where you can do your work.

You'll be working outside the REQUEST transaction at that moment, so please
keep that in mind when modifying objects.

Cheers
