Better yet would be a per-process *name* of the current working
directory stored somewhere, built according the the way you
happened to get there.  This would make getcwd() amount to printing
static data instead of the contortions it does now, and as a
side effect, it would make ".." mean something unsuprising in the
presence of linked directories.  Is there some reason this isn't done?
