Remind us again why we wouldn't be able to write a coroutines `Dispatcher` which uses `NSThread` on iOS?  I know objects, in native, are 'frozen' when crossing Threads; but as long as we respect that; i.e. treat all data arriving from `Channel`/`Flow` as immutable, would it work?  Or is coroutine context (or other internal coroutines machinery) violating this principle itself, such that it really couldn't work yet.

IMHO Any iOS/OSX coroutines `Dispatcher` should work with `NSThread` directly, and _not_ Apple's GCD.  GCD is itself a 'dispatcher'-like concept so the two layer redundant concept on each other to add complexity with little-to-no value.
