Thanks for the tip.  I already have something using these flags
implemented:

  PROMPT_COMMAND="$PROMPT_COMMAND;history -a; history -c; history -r")

which is a functional hack, for the most part.  It still has some of the
problems mentioned in my original message (history is only added to
after a command concludes, sporadic truncation still happens, etc), plus
this approach is rather ugly.

Thanks again, have a lovely day.
