I'm not sure what you mean by resetting the current working directory. When your script exits, its current working directory disappears with it, just like its environment. 
(fastolfe) eddie:~$ perl -e 'chdir("tmp"); system("pwd");'
/home/fastolfe/tmp
(fastolfe) eddie:~$ pwd
/home/fastolfe

There is also the Cwd module, which will fetch the current working directory (via getcwd or cwd). I don't know if/how these values are tainted though.
