For hard realtime systems most kinds of dynamic memory allocations are a no-go. A lot of programs with such requirements have everything statically allocated, others use some static memory pools and custom allocators that those. I think that should also work with D - with the problem of losing lots of the standard library. I think the most problematic area is somewhere in between: Applications that want a mostly realtime performance without having to put too much work on guaranteeing it (e.g. Games, Low Latency Audio Processing, ...).
