Processing tasks outside of janet_loop

[yrns]

I am embedding Janet in my application. I want to use the event loop to process scheduled tasks, but I don't want to block the main thread with janet_loop. I have my own loop that does other work in the main thread, as well as interacting with Janet. I can create fibers and continuously call janet_continue on them, but fibers spawned from Janet (say, a TCP server) won't ever make progress. I can run Janet in its own thread, but then I have to marshal everything in and out. I guess I'd like to be able to call janet_loop1 whenever I want. Any suggestions?
