Judging by how long the NS relayout code has been installed for, and how it has 
not actually caused problems in Fmemq, I'm inclined to wait for someone to 
complain about memq not working before we remove it.  I tried several months 
ago, and removing that call to redisplay resulted in the system refusing to 
resize the NS window.

The call to redisplay in the drag and drop code should not cause any problems, 
as that hook cannot be called from ns_read_socket.

Thanks.
