Yup, that's something I've had for a while for the same reason. I called 
it envreset since it's not only called after forking, but it's the same 

The clearing of redirlist is also what I ended up doing, except I did 
free the memory by adding a drop parameter to unwindredir and passing 
that on to popredir. That should not affect the user-visible behaviour.
