These are the last patches for now, and they're small. The base for
each of them is dovecot-1.1.7 + Apple patches 9 and 10, again not
because of a logical dependency but just because these patches change
parts of the earlier patches.
Patch #11 adds a few dtrace providers to key points in the code. We
are still validating the correct placement and usefulness of these.
One cool thing about dtrace is that when not in use the hooks
literally are just a couple of no-op instructions.
Patch #12 increases many listen queue sizes to handle high loads
better. The new values are not necessarily the best possible values
but they do allow more throughput.
Patch #13 makes dovecot adapt to dynamic host identity changes upon
config reload.
Patch #14 covers three miscellaneous changes, to support more file
descriptors and an "unlimited" number of mail processes, and a
different default mail user.
That's all our patches for now!
