Why the wait for reviews / advice from armbru?

[Markus Armbruster]

I've been dealing with a health emergency in the family.  I've had
serious difficulties focusing, patch review in particular.  I apologize
for letting you all down.

I tried to cc: the people who I believe are affected, but the list is
almost certainly incomplete.

While this situation persists, maintainers should feel free to merge
without an ACK from me when I'm too slow to provide it.
