we have the source - it looks like inherited stdlib from FreeBSD.

http://www.opensource.apple.com/source/Libc/Libc-498.1.7/stdlib/getenv-fbsd.c

however, more debugging is going to be needed..  I guess we're going to have to
look at what is set up for  at exit .. and if that's getting broken (or this is
revealing a lingering bug).
