This task was added in MDEV-32050. Previously this was part of the purge_coordinator_callback and executed less frequently.
Yet another thread is trying to write out pages of this undo tablespace:

So far, I failed to reproduce this locally by running 2,800 repetitions of the test on a local 32-bit build. I started another campaign of 56,000 repetitions, and it is over ¼ through, with no failures.
