Surely the validity check done by Python is more sophisticated than
this? Doesn't the binary file have to be compiled under the same python
version etc?

But Python proper is executing all the above anyhow isn't it? So the 20
msecs advantage I measured already includes this logic.

Anyhow, I give up. Compilation, it seems, only applies to python
modules. Compilation is not appropriate for Python scripts. Should be
in the FAQ.
