len(data) == cursize means that we're expecting that cursize bytes of the data arrive over the socket simultaneously, right?

Yes, and this assumption was incorrect. There was another bug in the old code -- it did not work on Linux without fork(), because read(n) could return less than n bytes. #119455 fixed it, and we need to preserve this fix. I restored that code and try another approach -- using non-zero timeout.
