Thanks for the review.
I was afraid that the differences would be noticeable but they aren't:
At least on my laptop, the differences between the patches are within
the noise:
# ./cat /proc/stat | grep ctxt;./osim 2 2 1000000 0 0;cat /proc/stat |
grep ctxt
runtime: stock patch 1 patch 1-4
2,0088875 2,041084 1,997367
# ./cat /proc/stat | grep ctxt;./osim 2 20 1000000 0 0;cat /proc/stat |
grep ctxt
4,32541 4,295956 4,277817
(assuming 2 cpus, otherwise increase "2" and "20" accordingly)
