Could you describe be "sometimes" occurrences? Does that happen through 
repeating a similar action several times? Or slightly different actions?

The process-environment setup seems fine. We did corrupt it in 1-2 
places in the past using 'setenv', but I don't see anything like that in 
the current codebase. And the effect would probably be different anyway.
