GFDL and deleted content 

Hello Jimbo, how does the GFDL handle deleted content? It seems to me that all GFDL contributions to wikipedia that aren't copyright violations themselves (or obvious vandalism too perhaps) would have to be saved and delivered by wikipedia somehow? What happens if an article exists for a few months and then for one reason or another it is deleted, doesn't the GFDL require wikipedia to in some way deliver that content to users? Just wondering.  T
