dict_view corrections were done in new fix (Thx for your findings). But there possible further issues with select.select usage. According official documentation https://docs.micropython.org/en/latest/library/uselect.html "..This function is provided by some MicroPython ports ..." so NOT all micropython versions can support it. Here you can be lucky or ...not.
Also within TIMERS.md I had mentioned other options of building timers for micropython. Just check please https://docs.micropython.org/en/latest/library/machine.Timer.html
If this option will be inconvenient for you just let me know - i will try to think about solution compatible for all micropython ports.

Additionally added support of cases when select.select wait is not supported by OS or micropython port.
Issue can be closed.
