Kevin O'Connor 1dee1ba64e queuelogger: Add support for background log writing 
Writing to the debug log can cause an unbounded delay due to disk IO.
This is particularly so on embedded machines such as the Raspberry Pi
that run on SD cards.  These log writing delays can cause problems for
the main processing threads.

The new "queuelogger" code forwards all the main thread log messages
to a queue, and a background thread writes the log messages from the
queue to the destination file.  This eliminates the IO delay from the
main threads.

README.md

Welcome to the Klipper project!

This project implements a 3d-printer firmware. There are two parts to this firmware - code that runs on a micro-controller and code that runs on a host machine. The host software does the work to build a schedule of events, while the micro-controller software does the work to execute the provided schedule at the specified times.

Please see the documentation for more information on running and working with Klipper.
