Now I recompiled ruby without threads:

Ruby  Patch Platform                     Seconds   Iterations/s
===== ===== ============================ ========= ============
1.8.6   111 i686-linux (gentoo)          32.801483 30486
1.8.6   111 i686-linux (gentoo -threads) 15.776961 63383

Wow, that's better. Since I only have a few packages compiled
with threads, I try to recompile them without.
