How do you think Unix.getcwd works?  Most Unix implementations don't
remember the character string used to set the working directory.
Getcwd() walks the directory tree.

Does the specification of the NAME function say how it should interact
with asynchronous renamings?  Must it always return the current name,
or can it just return the name used to open the file?  This goes
beyond Unix, since most OSes allow files that are open to be renamed.
However, if the current name must always be returned, it would be
difficult for Unix to support this.
