I am aware of this issue, however, reverting leaves us at the mercy of
problems on solaris.
I do plan to implement a write buffer, however, introducing that into
the 4.3.x branch is probably a bad idea at this late stage.
While I don't think that stream_set_write_buffer()/set_file_buffer()
having no effect is such a bad thing (most php scripts don't have any
need to call this function), I am concerned about the overall
performance of writes in the absence of a user-space write buffer.
So I'm looking into a solution at the moment; there is no need to update
the documentation at this point.
