Once they happen, everything is hosed: all subsequent tests fail.
This is sooooooo close to #17216 (unlinkat/EBUSY) that I'm 99.99% convinced it's the same bug, just a different manifestation (presumably because of new containers/whatever). If that turns out to be the case, I'll close this issue and merge these flakes there.
