hey gsf, there's a problem with the way you did foo
here's a sequence of commands / code that shows the problem
its a bug
patch is below
with ksh builtins like wc you should be able to do things like
wc /home/ced/prod4/test19/x//@//xattr
and you get a pwd that can be passed on to other processes and used
long after your process dies
/home/ced/prod4/test19/x//@//
