This will probably be difficult,
because the kernel API doesn't generate
any debugger info when a fiber is created.
To support this, a special drivers that intercepts
all these Fiber functions and calls the Debugger would be needed ...
Without it, GDB will continue to consider that you run a simple thread.
But I don't really understand what you mean by saying that it yields
inconsistent results.
Could you try to be a little more explicit ?
