Could Krom Support Concurrency?

Does Armory have any support for concurrency? I’m currently planning to target Krom in production so that is my primary concern. There is a Haxe libary for concurrency, but concurrency is, understandably, not supported for the Javascript target. Would it be possible to add some concurrency api to Krom, or is it not even necessary for one reason or another? Would it make sense as a new Kha API maybe?

Edit: After thought, this should probably go on the Kode forums.
