Kevin O'Connor 447125faae serialqueue: Eventually time out if unable to write CANbus messages ...

Klipper logs an error on a failed CANbus write.  Unfortunately, if the
bus becomes permanently disabled (eg, due to a user removing power to
devices on the CANbus) then it can result in the logs filling with
error messages.

Permanently disable the low-level processing of messages if CANbus
writes continually fail for at least 10 seconds.  This avoids filling
the log with redundant messages.
