Maybe this one?

This would be better. :) 

ps, Could you add the ability of yielding to the debug hook lua api in future ?

(for example, if a lua hook function returns true, we call lua_yield(L,0) in C hook )

It raise an error "attempt to yield across a C-call boundary", when calling coroutine.yield() in a lua hook function now.

This will be very useful to implement a debugger or a preemptive scheduler.
