I don't know anything about Xilinx/bitgen so I don't know why you end up
with the wrapped and unwrapped versions running.  That would be a question
for the Xilinx folks.  But if you just need to kill a process, you can
use '/bin/kill -f 504' in your example above.  That should kill the
Windows process for you.
