The way I see it, the freeze period is intended to stabilize libvirt
for the upcoming release; as such, changes merged during freeze
should ideally be exceedingly small and targeted.

Of course it's always a trade-off, and whether the positive outcome
outweights the risk of potentially introducing more issues is to be
decided on a case-by-case basis.

Is the patch fixing an issue that was introduced in this release?
Then it's probably worth merging it, because doing so avoids the
situation where we release known-broken software. Is it fixing a
long-standing issue, as is the case here? Then it can probably wait
until the next release.

I feel like this conversation has happened a number of times on the
list already. Perhaps it would be a good idea to try and converge to
a set of accepted guidelines that we can add to our existing
contributor-oriented documentation?
