I did try searching, but no luck. I guess nobody using ksh as their interactive shell is as lazy as I am.
Hopefully one of the ksh experts will get back to me after holidays. In the meantime, I realized that ksh does not actually need to execute a command in order to reload the history file: While typing Enter by itself does not trigger a reload, typing anything (even just a semicolon) followed by Enter does.
So it seems that ksh's default behavior when it comes to the history file is "append then reload". My question for the experts is whether there is a command does "just reload". I've already looked at the ksh man page and snooped around for options to the fc command, no luck. If there is such a command, adding it to my prompt_commands function (see my "On korn shell, how to share history..." thread--apparently I'm still too new here to share the link) should do the trick.

NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera-
tion are not performed.
