Yes. I have an old micro-benchmark (old, but extremely stable) that measures how many times "signal();kill(myself,..)" can be run per second :
With 2.1.130 : 164564..164606 loops/s With 2.1.130 + your patch : 164243..164329 loops/s
lat_sig (from lmbench) says : 2.1.130 2.1.130 + your patch Signal handler installation: 1.490us 1.490 us Signal handler overhead: 3.844us 3.854 us
So it look like micro-benchmarks agree with the simulation ;-)
