This branch (https://github.com/prohaska7/mariadb-server/tree/mdev-10327) contains a preliminary fix from George Lorch @ Percona, and has run 100's of iterations of the background_job_manager test on mariadb successfully. DB-1004 has a more complete bug fix.
The crash on mariadb occurs because a background job object is cancelled twice. This screws up the tokudb use count and causes the assert to fire. If the cancel logic is only run once, by checking if the background job object has already run the cancel logic, then the crash no longer occurs.
On a side note, this test runs fine (at least 200 iterations) on percona server 5.7. I suspect that the tokudb handler interface is being used slightly differently on mariadb compared with percona server 5.7.
