IDLE then produces a popup that says:
IDLE's subprocess didn't make connection. Either IDLE can't stat a subprocess por
personal firewall software is blocking the connection. <ok>

I think that life would be a whole lot easier for people if instead we got
a message:
Warning: local file /u/lac/junk/string.py shadows module named string in the
Standard Library
I think that it is python exec that would have to do this -- though of
course the popup could also warn about shadowing in general, instead of
sending people on wild goose chases over their firewalls.
Would this be hard to do?
Leaving IDLE aside, the reason '' is added to sys.path is so that people
can import their own modules. This is very useful. Shadowing is the
result of putting it at the front. I have long thought this a dubious
choice. If '' were instead appended, people could still import modules
that did not duplicate stdlib names. Anyone who wanted shadowing could
move '' to the front. But then shadowing would be intentional, not an
accident.
