  Thanks for bringing this up. Not yet, not yet. Following patch was
produced to fix another manifestation of the issue, hopefully forever:

  The idea is simple: if a var is marked as unexported, then it should
be unset unconditionally regardless of any other circumstances ;-).

  So, I hit this issue on a RedHat-based system (FC5). Otherwise, it
seemed to have worked on Debian/Gentoo systems.
