Just to clarify: changing the ABI in 3.[23] is out of the question.
We're trying to put as much as possible back into 3.3, but it's not
always possible to do this.
I think the state of this bug report is that for buffered io, 3.4 is
faster than 2.x. For unbuffered, 3.4 is slower than 2.x but less than
earlier 3.x releases.
