Why does the cached simulation kernel still need to be compiled?

[dsandber]

I'm using the render_on_macos.py example and noticed that I get the message "Compiling simulation kernels..." even when the previous run has ended with " Exiting Genesis and caching compiled kernels..." and the scene is unchanged.

The compiling takes 8 seconds. If I remove the cache, it takes 44 seconds, so apparently the cache is working.

Is the message wrong? Perhaps it should say "Loading cached compiled kernel" instead?
