        l = 0
        while True:
                if r == len(b):
                        final = False
                        l = 0
                        r = nbytes
                decoder.AcceptWaveform(b[l:r], final)

                l = r
                if l >= len(b):
                        break

                if r + nbytes < len(b):
                        r = r + nbytes
                else:
                        r = len(b)

t = threading.Thread(target=send)
t.start()
#send()
#decoder.Reset()
#decoder.Reset()
#send()

for res in decoder.GetInstanceResult():
        print(str(res))
t.join()

when gil is hold in send thread, these is no chance running "for res in decoder.GetInstanceResult():"
so if AcceptWaveform is passing to c++, c++ code should release gil lock in some way
