Could you please provide more information in the commit message?
E.g., what will happen if without this patch? Will it crash the
source or stall the source migration or others? Otherwise it's a bit

Normally I would prefer to not touch global states in feature specific
code path, but I'd like to know the problem more first...
Thanks,
