- RFC: make _fiber_start() return a handle on the fiber

You are right, this will not break existing code. Nevertheless, we
We're just returning a thread ID when we start a fiber now, you can
When we start a fiber via the _fiber_start() API family, we don'tSounds good, but we need to do it in away that keeps APIs
get back a handle on the created fiber. The fiber identifier is
actually the start of the fiber's stack. This hasn't been a
problem until now since no API requires a handle on the fiber,
except one, fiber_delayed_start_cancel(): that API is part of a
pair, where the other API, fiber_delayed_start() starts the fiber
and returns a handle.
However, Jukka asked me an API could be created that cancels a
fiber_sleep() call, something like fiber_wakeup(). The
implementation of such an API is very simple, but it requires a
handle on the fiber we want to wake up. This in turn requires the
signature of the _fiber_start() family to return a handle to the
fiber that gets started.
The signature of _fiber_start() et al. would then change from a
void return type to a void * return type.
Objections, comments, etc ?
compatible I guess.
ignore it. I don't see an issue here...
should track such API changes and document them in release notes.
