Compile a model to JitScriptModule like this:
jit_actor = t.jit.script(acc)

and call it like this:
future = [t.jit._fork(model, *args_list) for model, args_list in zip(models, args_lists)]

Then asynchronously wait for results:
result = [t.jit._wait(fut) for fut in future]

These APIs work outside of your JIT module.
