A reasonable suggestion, but these days it might be better to use
openat instead of chdir.  That is what CVS coreutils is doing.  (It
uses some new gnulib code to port to systems that lack openat.)

openat is currently only available in recent-enough versions of glibc
and Solaris, so the code is a bit slower elsewhere, but the difference
is not great and I don't think we need to worry overmuch about
performance on older systems.
