This Trac instance is not used for development anymore!

We migrated our development workflow to git and Gitea.
To test the future redirection, replace trac by ariadne in the page URL.

Implement a global task manager using a pool of worker threads

Tasks are simple callables (e.g. lambdas), and can be pushed with 2 priority levels. Pushing a task returns a future.
Futures can be waited on, can return results, and can be cancelled deterministically. Futures can also not be waited on.

This gives 'hardware concurrency - 1' threads to maximize CPU usage in a work-stealing workflow.
