How is Python supposed to do that without making a copy of every module and script it runs just in case it gets modified?

(That's not a rhetorical question -- if you can think of a cheap way to implement this, I'm listening :-)

99.99% of the time this would be a total waste of time, so this would be a very expensive exercise for very little gain. Python's startup time is already too slow without having to also make potentially hundreds of file copies every time you run a script.

For the record, I too once ran into this issue. It left me utterly confused for an hour or so until I worked out what was happening, and then I never made the mistake of editing a running script again.
