Is it possible to use std.experimental.allocator without the runtime or with the runtime disabled?

Is it possible to use std.experimental.allocator without the runtime or with the runtime disabled? It would be ideal for allocating audio buffers in the audio thread. malloc is tolerated but using a pre-allocated area with a fallback on malloc would be way better and faster too.
