OSError: [Errno 3] No such process

Is there a reason that that wrror message fills me with dread? Why is
the interpreter punishing me? What did i do wrong?

It always dies on the first use of the files that calls a directoy that
has a subpath. I tested that ability alone in the interpreter and it
worked perfectly well. I am on python 1.5.2 on a windows 98 box. I did
see aome comments on DejaNews about it, and it was also involving
os.listdir.. But there was only one instance, and i do not see precisely
how they relate...
