FWIW, in the staging tree they have a new tag for almost every day.
My linux repo currently has 677 tags. This same command would
probably take hours. I have not had the patience yet to let it
finish.
With your patch I get this.
$ time git tag --contains HEAD~200
v2.6.36-rc3
v2.6.36-rc4
v2.6.36-rc5
real 0m8.047s
