The MLKit Standard ML compiler has a region-based memory allocator 
that does no pointer tracing, so there are no unbounded pauses. (I 
think regions are typically called "arenas" by C programmers.) You 
can find the compiler at:


and there are also a number of papers describing the technique. The
developers advertise realtime programming as a possible application
domain for their compiler. However, I've never done any realtime
programming so I can't really evaluate the claim.
