Thanks. This is all well understood here.

Patches will be as small as possible, and we actually started the process
filing 3 code-reviews through the last month.
1 already integrated and 2 pending (D33868 and D34136).

My call for volunteers comes from the actual experience of trying to get attention
to these patches.

Not that I'm complaining... I'm just doing the math and see that 9 Aug is very close...

regards,
  Fedor.
