Eric, do not get it soo personally :) After all it is only a matter of
how we enjoy the process and have fun with the development.

Really, I appreciate your work and help, and likely this
misunderstanding happened because of a bad mix of the original bug and
this performance implication. Original bug has really nothing with what
we discuss here. And while the performance problem with bound sockets
creation may be visible, I did not observe it, while the idea
implemented with this approach shows up clearly in the graph I posted.
So I vote by both hands to further improve it by moving things around so
that there would be no unneded cache flushes during update of this
field.
