hm, one day, the great benchmarking will be a reason to use LLVM,
so, i think a bit more benchmarking info could be fruitful.
If test might be enveloped in a loop to get run about few
seconds then it makes hardly nightly testings much slower,
but will bring a lot of interesting info.

yesterday I got new SuSE 9.1 DVD, so i am going to enter this
river again. Perhaps, this time all will be fine.

Such an add-on would be really nice.
BTW, my good wishes to them concerning end-of-semester.
