error "throwing" and polling

[Ádám Peresztegi]

Hi,

TLDR - could someone help improving on these here? -> https://gist.github.com/flash42/4694896467562555d070

I've accumulated two problems after my first few days of writing async bacon.js code. 

1. I've tried to find a good solution for adding "user" errors to an EventStream - and propagating it. All this because I wan't to handle the errors later possibly at multiple clients. I've found a hack with flatMap but it's ... a hack I feel. (see gist)
   
2. I've implemented a polling logic checking the status of a RESTful service returning the status of a backend job. I've run into the problem of shutting down the polling and solved it with an "unsubBus". I'm wondering if this could be solved in a better way. (see gist)
