My (Linux 2.4.20) "man putenv" says, in part:

      The  putenv()  function is not required to be reentrant, and the one
in
      libc4, libc5 and glibc2.0 is not, but the glibc2.1 version is.

(PHP's putenv() function calls the underlying putenv() system call.)

What OS and web server are you using?
