[Nick Mathewson]

Update of /home/or/cvsroot/tor/src/or
In directory moria.mit.edu:/tmp/cvs-serv29558/src/or

Modified Files:
	control.c 
Log Message:
Replace an infinite-stack-recursion bug with a generate-infinite-debug-messages bug.  Maybe it isnt such a good idea to send LOG_DEBUG messages to the controller after all?
