That bug report lacks detail. There are already ways of sharing
history between multiple sessions. Some of the alternatives are
outlined here: 
https://unix.stackexchange.com/questions/1288/preserve-bash-history-in-multiple-terminal-windows

Give these a try first.

If you're interested in the implementation, review:

address@hidden:~/src/gnu/bash$ head -n1 bashhist.c builtins/history.def
==> bashhist.c <==
/* bashhist.c -- bash interface to the GNU history library. */

==> builtins/history.def <==
This file is history.def, from which is created history.c.

And if you want to go into even more detail, review the history
library as implemented by GNU readline (and bundled with bash):

address@hidden:~/src/gnu/bash$ head -n1 lib/readline/hist*c
==> lib/readline/histexpand.c <==
/* histexpand.c -- history expansion. */

==> lib/readline/histfile.c <==
/* histfile.c - functions to manipulate the history file. */

==> lib/readline/history.c <==
/* history.c -- standalone history library */

==> lib/readline/histsearch.c <==
/* histsearch.c -- searching the history list. */
