Cherrypicked 1af2217 to work around an infra flake.

After my infra cherrypick, all the tests completed, but the runner mysteriously exited with -5:

Looks like this is: flutter/flutter#157205,

So I am going to cherrypick https://github.com/flutter/engine/pull/55990/files to try to fix.

Any ideas on when this might get to stable?
It wasn't clear to me from the documentation how the release process for hotfixes worked after a cherry pick is merged.
