Trust me, the OS detection is happening, just not in your code. But that's not the problem.

It's all teh other stuff that is happening under the covers that you also don't know about.

This:

perl -E"system q[for /d %d in (scale-*) do @rd /q /s %d]"

Does the same job as this:

perl -MFile::Path -MFile::Spec -wE"File::Path::remove_tree(glob(File:: +Spec->catdir('.','scale-').'*'));"

But uses only 7% of the user cpu and 3% of the system cpu.

Does it matter? Depends alot on how big the trees are and how often you run the command I guess, but why use cycles you don't have to.
