Really interesting. 

Should we consider this to be an improvement towards the slow startup problem ? 

It seems to have really decreased the number of failed attempt to open files (ENOENT's appearing with strace upon startup) due to the interpreter default behavior for module loading on startup. (with a simple hello world I got 72 ENOENT's against 307 from default python installation on my standard ubuntu machine).

This problem mainly shows up when slow access storages are used (say raspberry + sdcard). Any chances you can provide this tool as prebuilt arm binaries ?

My assumptions may be all wrong, but anyway thanks for sharing your work. :)
