Bug with ussl and socket setblocking(False)

    Hello.
    I believe there is still a bug related to usocket and ussl libraries.
    If I use usocket for a connection (without use ussl to wrap it) I can use
    setblocking(False)
    and
    read() of usocket WITHOUT block the script

    If I wrap the socket (with wrap_socket of ussl module) and use read() of usocket library then the read function block my script.

    I read the documentation. The setblocking(False) of usocket is equivalent settimeout(0).

    So I think that wrap_socket of ussl module force the timeout of the socket, so setblocking(False) is useless.
    Is that correct? How I can use setblocking(False) with ussl and wrap_socket?
    I use setblocking(False) and setblocking(True) several times in my script before call read(), so I think I cannot set the timeout in the wrap_socket and call It before my read operations. Because it will work only before a connection I think.

    Thank you very much!
