Dan McGee 288a81d847 Use more efficient way of restoring working directory ...

Rather than using a string-based path, we can restore the working
directory via a file descriptor and use of fchdir().

From the getcwd manpage:
    Opening the current directory (".") and calling fchdir(2) to
    return is usually a faster and more reliable alternative when
    sufficiently many file descriptors are available.
