Note that the responses where all from just one user, so not exactly a broad feedback,
and their setup had almost no IO pressure going on, so rather a different issue (for
which we have an idea in the pipeline).

FWIW, I just moved that PBS version to no-subscription, so it wouldn't be testing
anymore.

I'll also ping this thread once the stop gap fix for the other issue, that we suspect
dea is hitting, is available in a packaged version; it'd just be interesting to know
if the general movement of IO operations to separate threads would have helped in your
big and (relatively) high IO pressure setup.
