Update of /home/or/cvsroot/src/or
In directory moria.mit.edu:/home2/arma/work/onion/cvs/src/or

Modified Files:
	connection.c dns.c 
Log Message:
do all the heavy lifting in connection_about_to_close_connection,
not in _connection_mark_for_close

this will hopefully clean up the huge cyclical function mess
