Why is it better to import from the current directory first? Windows
has that policy for executable commands; Unix, on the other hand,
requires that you put an explicit path for anything that isn't in the
standard search path. Which of these options is the more likely to
produce security holes and/or unexpected behaviour?

Welcome back to the list, Rick. Got any demonstrable code for Python 4000 yet?
