Highly recommend that the action proposed in #2 is taken. (If I
understand it correctly).

In my opinion: The 2020 version has nothing to do as main package for
ksh, and absolutely not in an LTS release.

As for the bug experienced by OP it is ugly. The history loading is
botched and have several bugs. When history reaches a limit of N bytes
it does no longer write to history file. It then opens a new file
descriptor to the history file for each command. On for example Linux
this can give something like:


        $ find /proc/PID-of-ksh/fd -lname '*/.sh_history' | wc -l
        746


(Opinion on the 2020 project) Sure there was honest intentions to make
it better, but from the looks of things there was very little
understanding and respect in the mix. It seemed more important to paint
Korn as a crazy spaghetti coder who obfuscate with intent – then
understanding the code. Think that is sad.
