Hi all!
v2: add fix:)
We've faced the following mirror bug:
Just run mirror on qcow2 image more than 1G, and qemu is in dead lock.
How long has the bug been present? Based on patch 1 mentioning commit
2e1990b26e5 (in 3.0), I'm guessing that this bug is not a regression
specific to 3.1? If so, then maybe we're better off deferring this to
4.0 just relying on qemu-stable (already cc'd); on the other hand, if it
is an easy-to-trigger deadlock on something the user is likely to do,
can we justify it being severe enough to warrant -rc4?
