Please no.

If your program wants to use the environment as an out-of-band global var for cross thread communication, you can make your own mutex.

That will break if any code which is not aware of the mutex calls getenv, even for a variable not related to the communication.

Of course. It’s a bad idea. If you modify it the environemnt becomes a global var.
