That's "just the way it works".  An executable is created with an initial 
current directory and can only change its own current directory.  The parent 
executable has its own current directory and it can't be changed by its 
child processes.  The parent has to set up a method for the child to tell it 
when it wants the parent to change, which is what you've set up in the 
scenario you described.
