There have been many ambitious projects being developed in other GCed languages. In Java one can see that there are implementations trying to support soft-realtime. Also concurrent GCs on multicore machines are provided, to lessen the problem of stalls due to GC. In the Common Lisp world the response have been sophisticated GCs or avoiding GCs. For example G2 is a tool to develop soft realtime expert systems - written in a Common Lisp implementation with lots of manual memory management. G2 is used to for process and production control applications.
