I like complicated.  :)  I have written a new version that makes copies
of all variables within the environment upon the first run of setenv().

Here are the two versions I have written to stop the memory leak.
Old (complex):  http://www.farley.org/freebsd/tmp/setenv-1.tar.bz2
New (simple):  http://www.farley.org/freebsd/tmp/setenv-2.tar.bz2
