I have frequently noticed GNU Screen with multiple Bash shells, each shell/tab, 
the history is routinely forgotten/lost.

A possible solution is to increase Bash history command and file size:

Here I increased from 150 to 15,000(lines/MB)

export HISTSIZE=15000
export HISTFILESIZE=15000

Sort of ridiculous, and I think the cause is more related to not safely exiting each shell/tab prior to halt.

Maybe the proper method to halt a system is to send a signal to GNU Screen, and place it within a halt.sh script?
