AFAIK, it can only "change" if the environment changes. Changing the process 
environment should only be done early in main().

If other threads already exists, it´s undefined behaviour anyway. If libraries 
(e.g. VDPAU) are already initialized, it´s likewise calling for big troubles.

So I don´t really see the point in this patch. If you fear that the 
environment changes, you need atomic access to the environment. And that´s 
essentially not possible with POSIX :-(
