This code actually sets this value whether called before, or after connect().

I think the comment should be something like:

"Locally cached value of buffer sizes, if set to a non-default value."

As we do not take care about "default" value here, I just said:
"Locally cached value of buffer sizes."
Please note that, this is actually used only "before" connect() in *this layer*,
unlike net/... changes I made in this CL.
