On linux the cwd is correctly set between fork and exec where it has no  
influence on the parent (racket) process. On windows the cwd is set in the  
parent before the call to CreateProcess. Is there any reason to not use  
the lpCurrentDirectory argument to CreateProcess to leave the parent  
untouched? This would prevent these unpredictable changes to the real os
