This didn't seem to do anything for me.....but I also did not try  
several times,  and now I'm having a hard time reproducing the  
problem. :(

One really odd thing that I did notice on my windows 2000 machines  
was that when I do a 'ps -ef' many times in a row quickly, the  
test_configure script that I'm using dies...it either segfaults or I  
get fork: Resource Temporarily unavailable.
