"Don't get discouraged - or impatient
------------------------------------

After you have submitted your change, be patient and wait. Reviewers are
busy people and may not get to your patch right away.

Once upon a time, patches used to disappear into the void without comment,
but the development process works more smoothly than that now. You should
receive comments within a week or so; if that does not happen, make sure
that you have sent your patches to the right place. Wait for a minimum of
^^^^^^^^^^^^^^^^^^^^^

one week before resubmitting or pinging reviewers - possibly longer during
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

busy times like merge windows."

+ the merge window just opened.

So stop the spamming please.
