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.
