I think this can be fixed by the user.  I set up one history file per tty,
so different windows have separate histories. If I do a shell escape from
some program, I have the history of that window.  Here are the necessary
lines from my .kshrc:

HISTDIR=/tmp/${LOGNAME:-$USER}
if [ ! -d $HISTDIR ] ; then /bin/mkdir $HISTDIR; fi
HISTFILE=$HISTDIR/`basename \`tty\``.khist
export HISTFILE
