1. How did you choose exactly these places to patch?
I see some other places, which also wait for an event,
but they still use a small timeout (in comparison with
240 secs). For example:

    socket.result line 233, 904, 919:
        s:readable(1)
        ---
        - true
        ...

    socket.result line 836, 848:
        s:readable(10)
        ---
        - true
        ...

    socket.result line 2870:
        s:settimeout(1)
        receive2 = s:receive('*a')

      Here :receive() has timeout 1 sec,
      not infinity.

2. Here the timeout was infinity, but you
changed it to your constant. Is it to make
all the places consistent? That is strange,
because there are still other places calling
writable() without arguments or a settimeout()
invoked beforehand.
