They hold a FileShare.Read handle and expect a delete or replace to fail;
Linux unlink and rename ignore open handles, so they can never pass there and
showed as three standing failures. [Platform("Win")] reports them skipped with
a reason on Linux and keeps them running on Windows. No Linux failure injection
exists: the store names its temp file with a fresh GUID and the suite is
likely root in the verify container, so read-only directories do not fail.
