Not seeing anyone else answering I will jump in even though I don't
share history myself and don't know this topic in detail.

Instead of using the debug trap I think it is much better to use the
PROMPT_COMMAND.

Setting your histo function in PROMPT_COMMAND instead of in the debug
trap would probably solve your problem.

  PROMPT_COMMAND='history -a;history -r'
