But when you use bigForth's own cd, it suddenly works:

cd /home
pwd /home

Think about it: The current working directory is a property of each process.  
If you call bash, and let it cd somewhere, the bash process changes its 
current working directory.  Exiting that, and you are back in Forth, with 
the same PWD as before.
