Also, i have some questions about the coroutines. because i will create and
dispose lots of coroutines, i have to implement a coroutines pool to
optimize this payload. it works fine when a coroutine ends normally, not
yielded, no errors. so I can recycle it into my pool. but when the coroutine
yields or errors, lua seemed saves the status and the stack of the
coroutine, and I didn't find a way to reset the coroutine to the initial
state, where I can put a new function to run. in this case, i have to
dispose the coroutine rather reuse in my pool. it still works fine now since
so far i don't need to terminate a yielding thread, but I guess this would
happen in some time... so I was wondering if there is a way to reset a
coroutine to the initial state, in 5.1 or any new functions will be
introduced to 5.2?
