Why doesn't Python remember the initial directory?

Why would you expect that it would?  What would it (or you) do with this 
information?

More to the point, doing a chdir() is not something any library code 
would do (at least not that I'm aware of), so if the directory changed, 
it's because some application code did it.  In which case, you could 
have just stored the working directory yourself.
