Any production release should be done Tue - Thu, if at all possible. But
for development release, like this RC, basically any day is good.

I really would like to have the RC out either tomorrow or Friday so that
we would get some testing ongoing during the weekend already. It has been
a while since the beta and pretty much all valid feedback on that has been
received long ago. Having much less that two weeks between RC and Final
most likely does not work as it takes some time to get the feedback - and
making the final release the last week before holidays does not sound
tempting at all.

So I would be inclined to say we have this bug in the known issues and get
the RC out Thursday or Friday, unless there is something new that makes it
impossible. Especially since the issue apparently does not happen in the
reference configurations and can be worked around, I do not see this a P0
/ blocker for the RC.

Yours,
