We tested gin with 5 millions records (but not a wikipedia's text, but with blog 
records which is usually mush shorter) and index creation time was near 8 hours 
on Dual Xeon 3.2, but we didn't try GiST. In other hand, creating GiST index on 
0.5 millions emails took about 12 hours.

That's why 7 minutes is very suspicious result.
