switch does not propagate cancel requests across switch boundary?

When switch swaps the new stream with the old the cancel propagation terminates on a switch boundary, so if the inner stream was itself created through a switch operator, the inner stream associated with the inner switch is never canceled. This is different than the behavior in both Rx 4 and xstream.

Isn’t this a bug?

@ntilwalli Thanks for all the additional info. I haven’t had a chance to dig into it, but it seems like there’s some sort of race condition related to the end of stream handling in switch. I should have time soon to look into it more.

@ntilwalli Your example seems potentially interesting. However, there are a couple things about it that make it harder to understand what is going on and whether there’s actually a problem. First, there’s just a lot going on in it, and second, it’s fairly different from either the rx or the xstream examples. Could you try to simplify it, i.e. try to find a more minimal example of the problem you think you’re seeing? I think that will help us figure out what’s going on. Thanks!
