--- Comment #2 from Walter Bright <bugzilla at digitalmars.com> ---
I'm not suggesting fixing the cause, I realize it is not under our control.
What I suggest is for these sorts of errors, have that test case automatically
retried after sleeping for a minute or so.

If it keeps failing after multiple tries, then stop.
