[WIP] xdist custom bin packing

[roddajohn]

Thanks for submitting a PR, your contribution is really appreciated!

Here's a quick checklist that should be present in PRs:

• Make sure to include reasonable tests for your change if necessary

• We use towncrier for changelog management, so please add a news file into the changelog folder following these guidelines:

  • Name it $issue_id.$type for example 588.bugfix;

  • If you don't have an issue_id change it to the PR id after creating it

  • Ensure type is one of removal, feature, bugfix, vendor, doc or trivial

  • Make sure to use full sentences with correct case and punctuation, for example:

    Fix issue with non-ascii contents in doctest text files.

This seems like a attempt for something larger

It's critical to have some design discussion and buy in from the maintainers to avoid doing a great amount of work that turns out unmerged

Definitely. I will close the PR for now to stop the stream of notifications.

Oh sorry y'all, honestly was just looking for the diff.

For that you might open a PR to your own fork's master branch. 👍
