@axic , what’s your disposition on this issue and the proposed fix?

I’m using the changes from @tzapu 's PR #229 , which seem to include your own changes as well, and it’s all working for my purposes.

I’d love to see the fix merged into master so that I can go into production with my own development that’s depending on it, and I see @snd and others are waiting on it as well.

Are there any reservations you have? Is there anything we can do to help facilitate?
