Metadata handling has been moved to its own thread so I'm pretty sure
that changes your failure scenario sufficiently.

What's the big deal with upgrading? The work for doing the testing you
already did, with additional plumbing for a workaround seems to me
not less than upgrading the IdP itself. Which, btw, is the only way
to get rid of any and all known security issues affecting your
version.
