We see tests fail because of disk stalls with some regularity, and there's a sense that they happen more than is acceptable. We have a support ticket with GCP [1]. According to their support team, we are expected to see improvements in this area 4-6 weeks after Feb 16 -- in other words, we expect these issues to not come up nearly as often by early April at the latest.

This issue is for us to keep track of disk stall failures (by mentioning this issue on failures caused by disk stalls) and to make sure we check on the progress of the fix and close it when we think it's resolved.
